The invention of tiny devices capable of precisely controlling the direction and behavior of light is essential to the ...

A new metasurface design lets light of different spins bend, focus, and behave independently—while staying sharp across many ...

A frequency comb is a spectrum of evenly spaced, phase-coherent laser lines, that acts like a ruler to measure the frequency of light with extreme precision. The dual-comb technique does not suffer ...

Researchers propose a method to detect and map low-frequency excitations in nonlinear materials at nanometer resolution, ...

…and Stanford launches “micro” frequency comb, as basis for mass-market adoption of such devices. An ultraviolet photon-counting dual-comb spectrometer. Scientists in the group of Nathalie Picqué at ...
