Two aspects of dark points in light
If you shine a laser pointer on a rough surface, you will notice that the reflected light creates a constellation of bright spots. However, less visible among these bright spots are threads of darkness known as optical singularites. Historically, these...

Dr. Aun Zaidi and Dr. Dmitry Kazakov successfully defend theses!
We congratulate Dr. Dmitry Kasakov and Dr. Aun Zaidi on successfully defending their PhD theses and graduating this spring! In their time in the Capasso group, Dmitry has been working on active nonlinear mid-infrared photonics and Aun has been working on...
Aun, Federico and Dima after both have successfully defended their theses.

Sydney Mason receives Thomas Temple Hoopes Prize and Dean's Award
Graduating senior Sydney Mason has received the prestigious Thomas Temple Hoopes Prize and Dean's Award for Outstanding Engineering Project for her project "Microscale Metasurface Intracavity Holographic Display". She has also published part of her work...

Using resonances as synthetic helicity for optical manipulation
Research on spin-orbit interactions in evanescent fields is crucial as it could revolutionize particle manipulation using light. This research, led by Dr Jinsheng Lu and published in Physical Review Letters, has uncovered a new kind of optical force that...

3D Holography with Light Sabers
Displaying virtual 3D objects with light using computer-generated holography is at the heart of AR/VR and the metaverse. Current methods display virtual 3D objects by projecting many image slices, parallel to each other, and to the plane of the display —...

EUV-ureka! A hole new world
Metalenses have revolutionized the way we control visible and infrared light, with numerous applications in research and technology. However, it has been challenging to use them for extreme ultraviolet (EUV) light, which has much smaller wavelengths...
