Physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a compact laser that emits extremely bright, short pulses of light in a useful but difficult-to-achieve wavelength range, packing the performance of larger photonic devices onto a single chip.

A new active metasurface, the electrical-programmable graphene field effect transistor (Gr-FET), from the labs of Sheng Shen and Xu Zhang...

“This is a feat of nanotechnology at the highest level,” said senior author Federico Capasso. “It opens up a new way to structure light...

Researchers develop new design and fabrication method to make lightsails for interstellar travel

Researchers developed a compact, solid-state laser system that generates 193-nm coherent light — the first 193-nm vortex beam

For the first time, researchers have used high-speed laser writing to create lines spaced just 100 nm apart on a glass substrate. The optimi
