Capasso Group
Welcome to the Capasso Group!
Metalenz: the Harvard Capasso group start-up
Read the story about Flat Optics, Professor Capasso, and Metalenz at the Harvard Gazette and his interview with Nature Photonics on Metaoptics for the consumer market.
Metalenz and UMC will fabricate mass-market metasurfaces in Singapore (Metalenz press release, Forbes article).
Find out more about Metalenz here: https://www.metalenz.com/. Also see a press release from the Harvard Office of Technology Development, a New York Times article, IEEE Spectrum, and an SPIE news article.

Q-ing Up Better THz Sensors: guided-mode resonances in thin-film metagratings
Detecting trace amounts of molecules—from explosives to biomarkers—requires highly sensitive sensors. Many molecules exhibit characteristic vibrational and rotational modes in the THz range, providing molecular fingerprints for label-free spectroscopic...
Bright, stable frequency combs enabled by racetrack quantum cascade lasers
Harvard researchers and collaborators at TU Wien have developed a racetrack-shaped quantum cascade laser that generates bright, stable mid-infrared frequency combs on a chip, opening a path toward compact dual-comb spectrometers for gas sensing and...
First demonstration of the structured Montgomery effect in free space
In the latest publication from our group, Murat Yessenov and colleagues have experimentally demonstrated the Montgomery effect, a long-predicted optical phenomenon in which structured light repeatedly defocuses and refocuses in free space without lenses...
Special Issue of Nanophotonics in honor of Federico Capasso
Nanophotonics has dedicated its latest special issue to Professor Federico Capasso, recognizing his pioneering work and his ongoing influence across the field. The issue features 47 invited papers from groups across the community, along with anecdotes and...
Graph‑Engineered Metasurface Packs Quantum Optics onto a Single Chip
Quantum photonics promises room‑temperature quantum computers and ultra‑secure networks, yet today’s systems still rely on bulky forests of lenses, mirrors, and beam splitters that are hard to scale. Kerolos M. A. Yousef and colleagues in the Capasso and...
Tunable Ring Laser Chips Broaden Mid-Infrared Wavelength Control
Tunable semiconductor lasers are vital for applications ranging from high-speed telecommunications to gas sensing and medical diagnostics, but existing devices face trade-offs in tuning range, accuracy, and complexity. Theodore P. Letsou, Johannes...
