�鶹��Ѱ��Boulder researchers have built high performing optical microresonators opening the door for new sensor technologies.

At its simplest form, a microresonator is a tiny device that can trap light and build up its intensity.

Once the intensity is high enough, researchers can perform unique light operations.

“Our work is about using less optical power with these resonators for future uses,” said Bright Lu, a fourth-year doctoral student in electrical and computer engineering and a lead author on the study. “One day these microresonators can be adapted for a wide range of sensors from navigation to identifying chemicals.”

For this endeavor published in Applied Physics Letters, the team focused on ‘racetrack’ resonators, named for their elongated shape that resembles a running track.

Specifically, researchers used ‘Euler curves’ — a type of smooth curve also found in road and railway design. Just as cars can’t make sharp right-angle turns in motion, light can not be forced into abrupt bends.

“These racetrack curves minimize bending loss,” said Won Park, Sheppard Professor of Electrical Engineering, a co-advisor on the study. “Our design choice was a key innovation of this project.”

By guiding light smoothly through the resonator, they dramatically reduced light loss, allowing photons to circulate longer and interact more strongly inside the device.

If too much light is lost, Lu says, high light intensities can’t be achieved for these microresonators to operate at the needed performance.

Made in Colorado

Incredibly small in size, the microresonators were built using the Colorado Shared Instrumentation in Nanofabrication and Characterization (COSINC) clean room’s new electron beam lithography system.

The facility provides a highly-controlled environment required to work at the microscopic scales that can lead to reliable device performance.

Many optical and photonic devices are smaller than the width of a piece of paper, meaning even tiny dust particles or surface imperfections can disrupt how light travels through a material.

“Traditional lithography uses photons and is fundamentally limited by the wavelength of light,” Lu said. “However, electron beam lithography has no such constraint. With electrons, we can realize our structures with sub-nanometer resolution, which is critical for our microresonators.”

For Lu, the hands-on fabrication process was a fulfilling aspect of the project.

“Clean rooms are just cool and you’re working with these massive, precise machines and then you get to see images of structures you made only microns wide. Turning a thin film of glass into a working optical circuit is really satisfying.”

A key success from the work was the ability of the researchers to use chalcogenides, a broad term encompassing a family of specialized semiconductor glasses.

“These chalcogenides are excellent materials for photonics because of their high transparency and nonlinearity,” said Park. “Our work represents one of the best performing devices using chalcogenides, if not the best.”

Chalcogenides were helpful since they have strong transparency for light to pass through the device at high intensities needed for microresonators.

However, the materials are not easy to process for the device, so there’s a balancing act to tread.

“Chalcogenides are difficult, but rewarding materials to operate for photonic nonlinear devices,” said Professor Juilet Gopinath, who has worked on this project with Park for more than ten years. “Our results showed that minimizing the bend loss enables ultra-low loss devices comparable to state-of-the-art in other materials platforms.”

Measuring light at the microscale

Once fabricated, the microresonators were handed off for testing, work led by James Erikson, a physics PhD student specializing in laser-based measurements. He carefully aligned lasers with microscopic waveguides, coupling light into and out of the device while monitoring how it behaved inside.

They looked for ‘dips’ within the data in transmitted light that indicate resonance as photons get trapped. By analyzing the shape of those dips, they were able to extract properties like absorption and thermal effects.

“The most obvious indicator of device quality is the shape of the resonances and we want them to be deep and narrow, like a needle piercing through the signal background,” said Erikson. “We’ve been chasing this kind of resonator for a long time, and when we saw the sharp resonances on this new device we knew right away that we’d finally cracked the code.”

Erikson added, to make a good device you need to know how much light will be absorbed versus transmitted. Thermal effects become important when adding laser power as you run the risk of damaging the device.

“The way most materials interact with light also changes depending on the temperature of the material,” said Erikson, “so as a device heats up its properties can change and cause it to work differently.”

In the future, the microresonators could be used for compact microlasers, advanced chemical and biological sensors and even tools for quantum metrology and networking.

“Many photonic components from lasers, modulators and detectors are being developed and microresonators like ours will help tie all of those pieces together,” said Lu. “Eventually, the goal is to build something you could hand to a manufacturer and create hundreds of thousands of them.”

How one engineering alum optimizes clean energy operations before they break

How one engineering alum optimizes clean energy operations before they break Charles Ferrer Thu, 02/05/2026 - 16:04

When Aoife Henry isn't leading her energy optimization company, she enjoys trail running wherever she goes.

Aoife Henry (PhDElEngr‘24) is optimizing technology for wind and solar energy operations.

The doctoral graduate is leading Zentus, a startup she founded that addresses a critical challenge in the energy sector: how to prevent costly equipment failures that can bring wind and solar farms offline without warning.

Her solution uses machine learning to forecast when and how defects in wind turbine blades and solar panels will develop, notifying operators to plan repairs proactively rather than react to emergencies.

“We’re trying to model how defects like cracks on blades will develop and impact power output so operators can prepare proactively,” said Henry. “Spontaneous failures are incredibly expensive.”

The stakes are particularly high for offshore wind installations, where Henry sees the greatest market opportunity. Repairs cost approximately $250,000 per day, individual turbine blades run around $6 million and complete turbines cost about $20 million. For solar energy, they are maximizing the maintenance of solar panels to limit how much time they spend offline. The less time panels are offline, the more power can be generated.

For operators managing these massive technologies, the ability to anticipate maintenance needs could translate to millions in savings while improving energy reliability.

Zentus currently offers two key capabilities: categorizing defects and assigning risk scores and forecasting how those defects will impact power generation. These tools will help engineering teams decide whether to repair, replace or simply monitor equipment within specific weather conditions.

Currently, Zentus is running three pilot programs, two in the United States and one in the United Kingdom. They aim to launch their product commercially later this year while actively fundraising to support continued development.

From �鶹��Ѱ��Boulder to Silicon Valley

After participating in the Ascent Deep Tech Accelerator, a �鶹��Ѱ��Boulder program that helps university researchers commercialize their technologies, Henry landed a fellowship with the Stanford Sustainability Accelerator at the Stanford Doerr School of Sustainability.

Launched in September 2024, the Stanford accelerator supports early-career scientists working to translate sustainability research into real-world impact. The program provides fellows with research and development funding.

Aoife Henry and her fiancé, Zach Schwartz, currently an ecology and evolutionary biology PhD candidate at �鶹��Ѱ��Boulder.

“I had a great advisor, Professor Lucy Pao, who always kept an eye out for opportunities,” said Henry. “�鶹��Ѱ��Boulder helped me build a strong application through programs like Venture Partners and the NSF I-Corps.”

After defending her dissertation, Henry drove straight to California and assembled a five-person team, including a �鶹��Ѱ��Boulder master’s student she had previously worked with.

Henry’s commitment to clean energy was shaped throughout her entire academic trajectory. After completing her master’s degree, she received offers from three PhD programs but chose �鶹��Ѱ��Boulder specifically for its wind energy research. On top of that, Henry won first place in the 2025 Three Minute Thesis competition on campus for her talk titled, Directing Wind Turbines with Foresight: The Shepherd and the Sheepdog Find a Crystal Ball.

“There’s no doubt clean energy will always matter,” she said. “We’re not going back to a de-electrified world and we can’t reach carbon reduction targets without transforming the electricity industry.”

While Zentus launched with a focus on wind turbines and solar panels, the company is already expanding its work on storage systems.

Energy storage is essential for renewable energy because weather-dependent sources like solar and wind require support to keep supply and demand balanced on the electric grid.

While lithium-ion batteries currently dominate due to cost advantages, Henry notes that longer-duration storage technologies and solutions continue to emerge.

“Our team has strong backgrounds in wind, storage and renewable systems,” said Henry. “In the long term, we hope to apply our tools to energy storage to reduce downtime and costs.”

As climate challenges accelerate and the world leverages renewable energy, innovations like those emerging from Zentus will be key to building a reliable, sustainable power infrastructure.

“Contribution is a core value of mine whether it’s to the planet and people. I want to contribute to the clean energy transition and our work of improving the reliability of renewables and energy storage supports that mission.”

�鶹��Ѱ��Boulder researchers have introduced a solution to improving the performance of large-scale desalination plants: stimulated Raman scattering (SRS).

Published Dec. 16 in the journal Environmental Science & Technology, the laser-based imaging method allows researchers to observe in real time membrane fouling, a process where unwanted materials such as salts, minerals and microorganisms accumulate on filtration membranes.

Worldwide, 55% of people experience water scarcity at least one month a year and that number is expected to climb to 66% by the end of the century.

Desalination—turning saltwater into fresh water—is critical for communities globally as demand increases.

Modern reverse osmosis (RO) plants make up about 80% of the world’s desalination facilities, placing greater importance on having them run efficiently.

“Reverse osmosis membranes are critical for desalination,” said Juliet Gopinath, professor of electrical, computer and energy engineering and physics. “Our work aims to monitor and provide early warning for membrane fouling.”

RO systems rely on thin polymer membranes to filter out buildup.

This accumulation reduces filtration efficiency and increases both energy use and operating costs for desalination plants.

Detecting fouling early remains one of the biggest challenges in desalination.

“We can learn a lot about materials and molecules by shining light on them,” said Postdoctoral Researcher Jasmine Andersen. “Depending on the type of light you use, you’ll get different light coming back, and that tells you what’s inside the material.”

This principle underlies Raman scattering, where the color—or wavelength—of the scattered light shifts in ways that reveal a material’s molecular structure and composition.

The team used SRS to observe crystal growth on RO membranes, tracking how the molecules vibrated revealing the chemical makeup of the material.

To test the system, researchers observed calcium sulfate and calcium bicarbonate, ions commonly found in seawater. SRS provided both high-speed imaging and chemical identification.

“Watching these crystals form as it happens, getting volumetric data and identifying the chemical all at once is pretty exciting,” Andersen said. “Previously, you could get volume data or chemical identification, but not at the same time.”

Andersen notes this level of insight is something industry tools cannot currently provide.

Supporting sustainable water systems

Understanding what forms on a membrane and when can help operators maximize filtration, notes Professor Emeritus Alan Greenberg, an expert in membrane performance and characterization.

“It is well known that RO desalination plants can be more productive and operate at lower cost if fouling is reduced and cleaning is more efficient,” Greenberg said.

Beyond calcium sulfate, the team expects SRS could help study more complex mixtures of organic, inorganic and biological materials that contribute to fouling in both seawater and brackish water systems.

“As our freshwater resources shrink, we’re going to rely more on desalination,” Andersen said. “If we can make that process more efficient and sustainable, we can help ensure people have reliable access to clean water.”

Key collaborators on this project included Victor Bright, professor of mechanical engineering; Y. Lange Simmons physics doctoral graduate; and Mo Zohrabi, senior research scientist. This project received funding from the Advanced Research Projects Agency-Energy, the National Science Foundation and a �鶹��Ѱ��Boulder Research and Innovation Seed Grant.

�鶹��Ѱ��Boulder researchers have developed a laser-based imaging method called stimulated Raman scattering to improve the performance of desalination plants by allowing real-time detection of membrane fouling. The advance could help make desalination more efficient and reliable as global demand for clean water rises.

Tiny new device could enable giant future quantum computers

Researchers have made a major advance in quantum computing with a new device that is nearly 100 times smaller than the diameter of a human hair.

Published in the journal Nature Communications, the breakthrough optical phase modulators could help unlock much larger quantum computers by enabling efficient control of lasers required to operate thousands or even millions of qubits — the basic units of quantum information.

Critically, the team of scientists have developed these devices using scalable manufacturing, avoiding complex, custom builds in favor of those used to make the same technology behind processors already found in computers, phones, vehicles, home appliances — virtually everything powered by electricity and even toasters.

Led by Jake Freedman, an incoming PhD student in the Department of Electrical, Computer & Energy Engineering; Matt Eichenfield, professor and the Karl Gustafson Endowed Chair in Quantum Engineering; and collaborators from Sandia National Laboratories, including co-senior author Nils Otterstrom, they created a device that is not only tiny and powerful, but also practical and inexpensive to mass-produce.

Their device uses microwave-frequency vibrations, oscillating billions of times per second, to manipulate laser light with extraordinary precision.

These ultra-fast vibrations give researchers direct control over the phase of a laser beam, allowing the chip to generate new laser frequencies with high stability and efficiency, all essential for building quantum computing, quantum sensing and quantum networking technologies.

Why quantum computers depend on precise optical frequency control

Among the leading approaches to quantum computing are trapped-ion and trapped-neutral-atom systems, which store information in individual atoms.

To operate these qubits, researchers “talk” to each atom using precise laser beams, allowing them to give the instructions to do computations.

Each laser’s frequency must be tuned with extreme accuracy, often to within billionths of a percent or even smaller.

“Creating new copies of a laser with very exact differences in frequency is one of the most important tools for working with atom- and ion-based quantum computers,” Freedman said. “But to do that at scale, you need technology that can efficiently generate those new frequencies.”

Today, those frequency shifts are made using bulky table-top devices that consume significant amounts of microwave power.

Current setups work well for small lab experiments and quantum computers with small numbers of qubits, but they cannot scale to the tens or hundreds of thousands of optical channels required for future quantum computers.

“You’re not going to build a quantum computer with 100,000 bulk electro-optic modulators sitting in a warehouse full of optical tables,” Eichenfield said. “You need some much more scalable ways to manufacture them that don’t have to be hand-assembled and with long optical paths. While you’re at it, if you can make them all fit on a few small microchips and produce 100 times less heat, you’re much more likely to make it work.”

The device can generate new frequencies of light through efficient phase modulation that consumes roughly 80 times less microwave power than many commercial modulators.
Using less power reduces heat and allows many more channels to be placed close together, even on a single chip.

Together, these features turn the chip into a powerful, scalable system for managing the complex dance that atoms must perform to make quantum computations.

Built using the world’s most scalable manufacturing technology

One of the most significant aspects of the project is that it was produced entirely in a "fab" or foundry, the same type of facility used to make advanced microelectronics.

“CMOS fabrication is the most scalable technology humans have ever invented,” Eichenfield said.

“Every microelectronic chip in every cell phone or computer has billions of essentially identical transistors on it. So, by using CMOS fabrication, in the future, we can produce thousands or even millions of identical versions of our photonic devices, which is exactly what quantum computing will need.”

According to Otterstorm, they’ve taken modulator devices which were previously expensive and power hungry and made them more efficient and less bulky.

“We’re helping to push optics into its own ‘transistor revolution’, moving away from the optical equivalent of vacuum tubes and towards scalable integrated photonic technologies,” Otterstorm said.

The team is now developing fully integrated photonic circuits that combine frequency generation, filtering and pulse-carving on the same chip, bringing the goal of a complete operational chip closer to reality.

Moving forward, they will collaborate with quantum computing companies to test versions of these chips inside state-of-the-art of trapped-ion and trapped-atom quantum computers.

“This device is one of the final pieces of the puzzle,” Freedman said. “We’re getting close to a truly scalable photonic platform capable of controlling very large numbers of qubits.”

This project was supported by the U.S. Department of Energy through the Quantum Systems Accelerator program, a National Quantum Initiative Science Research Center.

Researchers have developed a device that can precisely control laser light using a fraction of the power and space required today. Because it can be manufactured just like modern microchips, this tiny device could unlock quantum computers capable of solving problems far beyond the reach of today’s technologies.

Anika Mathur

Anika Mathur, a fourth-year electrical engineering student, has earned the fall 2025 Community Impact Award from the College of Engineering and Applied Science.

The award recognizes graduating undergraduate students who contribute to improving their community at the department, program, college, university and community level.

Mathur has served as treasurer for the Society of Women Engineers (SWE) and Engineers Without Border (EWB) since September 2023.

“Anika leads by example, inspiring others to take action while fostering an inclusive environment,” said Professor Melinda Piket-May. “Through her leadership roles, she promotes collaboration and encourages participation from students of all backgrounds. By modeling these values, Anika strengthens the college community and sets a standard for future leaders.”

Mathur’s impact with other student organizations supported by the Campos Student Center has spread positive ripples for their leadership boards.

“Anika has mentored multiple students into leadership roles and actively promotes collaboration between student organizations,” said Amanda McKenzie, coordinator of student societies. “Her financial expertise has made her a trusted student leader. She also ensures that all students feel welcome, often going out of her way to engage quieter or newer members in conversation.”

We sat down with Mathur as she reflected on her leadership and community involvement at the college.

You’ve mentioned that your community journey started before you even arrived at �鶹��Ѱ��Boulder. How did that experience shape everything that followed?

When I visited �鶹��Ѱ��as a high school senior, I attended Mocktail Night, an event for admitted students hosted by SWE and the dean’s office. The women I met that night inspired me so much and they were the reason I chose CU. I walked away feeling seen, welcomed and reassured that I could belong here. That moment stayed with me. So, when I came to campus as a first-year student, I sought out SWE at the Be Involved Fair on my very first day because I wanted to join the community that had already made such an impact on my life.

Your involvement with SWE has grown significantly over the years. What has that experience meant to you?

Early on, I went to as many SWE events as possible from friendship bracelet nights to resume reviews. By the end of that year, I wanted to help build the same supportive space I had benefited from. Becoming director of events allowed me to create welcoming environments through our weekly “Totally Tuesday” meetings. Now, as Treasurer for a second year, I help maintain the organization’s financial health and guide committees in planning events that bring women engineers together. What I value most is helping others feel encouraged and confident. Engineering can be overwhelming, and sometimes the most meaningful impact comes from checking in on someone who looks uncertain or saying “I’ll go with you” to a first-time attendee.

You also hold a major role in Engineers Without Borders. What has your work on the Nepal team taught you?

EWB has taught me how important it is to slow down and listen before deciding what “help” looks like. We work with communities, not for them, and that approach has changed the way I think about engineering. It’s not just about designing a solution, it’s about understanding people’s needs, priorities and perspectives. Being able to support that kind of long-term, relationship-focused work means a lot to me.

Tell us more about your STEM outreach work with TeachEngineering. What impact did that have on you?

Creating hands-on STEM education videos for the TeachEngineering Digital Library allowed me to reach K-12 teachers and students across the country. Knowing that these videos might be the first time a student sees engineering is incredibly meaningful. Not everyone grows up knowing an engineer, so if a student watches an experiment and thinks, “Maybe I could do this too,” then I’ve made a difference.

What drives you to show up for your communities?

It honestly has been rooted in creating spaces where students can grow with confidence, especially during moments when engineering can feel overwhelming or isolating. Some of the most meaningful contributions happen in the small moments: showing up consistently, checking in when someone seems unsure, saying “I’ll go with you to this event,” or simply making room for someone to try something new. Those moments build trust and connection. I hope to continue creating communities where we lift one another up, celebrate each other’s achievements and move forward together.

What are some of your favorite aspects about the ECEE department during your undergraduate career?

One of my favorite parts of the ECEE department has been how genuinely inclusive it feels. Even though the field is very male-dominated, I’ve never felt lesser than my peers here and a huge part of that is because our professors and staff are intentional about creating a welcoming, encouraging environment. I’ve also received an incredible amount of support throughout my time in the department, from professors who take time to help you truly understand the material to advising staff who always make sure you’re on the right track. That level of support has meant everything and has shaped a big part of my experience.

What about electrical engineering excites you?

I love how versatile electrical engineering is. There are so many directions you can go and the skill set opens doors in almost every industry. That range keeps the field exciting for me. I also love the mix of theory and hands-on problem-solving. Electrical engineering gives you the tools to build meaningful, real-world technology while still leaving endless room to explore.

What advice would you give future engineering students who want to make an impact?

My advice to future students is that if you want to make an impact here, start small. Just show up. Walk into that first meeting, even if you feel nervous. Ask someone how they’re doing, and really listen to the answer. Say yes to opportunities that feel new or a little uncertain. Community is built through consistent, simple acts of showing up for each other.

Lead with kindness. Engineering is challenging, and people often carry more than they let on. A supportive word, a shared moment or a genuine conversation can make a real difference. Surround yourself with people who encourage you, and be that source of encouragement for others too.

And most importantly: you are already enough. You don’t need to prove that you deserve to study engineering, you already do. What matters is that we keep lifting each other up, step by step, so we all continue to grow, learn and shine here. The most meaningful part of my experience at �鶹��Ѱ��has been the people and the community we’ve built together. Being part of helping others feel supported, confident, and valued is something I am genuinely proud of, and I hope every student who comes after me carries that forward.

What’s next?

I’m continuing my studies in the Bachelor’s–Accelerated Master’s Program at �鶹��Ѱ��Boulder to complete my master’s in electrical engineering with a concentration in high speed digital engineering. After that, I hope to work in industry, likely in hardware or signal integrity. I really enjoy the intersection of engineering and people, so I’d love a role that lets me solve technical challenges while working closely with others.

I’d love to thank the people who’ve supported me throughout my journey. I’m incredibly grateful to Professor Piket-May and Professor Bogatin for their guidance, as well as the advising staff who have always been there to help. I also want to thank Amanda for her constant encouragement and for creating such a supportive environment for all of our student orgs. Most of all, I want to thank my fellow SWE board members. They have been my strongest support system, and I truly couldn’t have gotten here without them. Their teamwork, kindness and friendship have made this experience meaningful and I’m grateful for everything we’ve built together.
