Rochester researchers combine ultrafast light gating and AI to improve near-infrared imaging through scattering materials.

Researchers from the University of Southampton (UK), and the Institut d'Optique in Bordeaux (France) have devised a new approach for controlling light in a silicon chip by bringing the concept of ...

Tiny manufacturing imperfections in optical components normally go unnoticed. Yet they can alter light in surprisingly ...

A laser does not always need a perfectly repeating pattern to produce a clean beam.

A simple, cheap, and highly effective approach to achieve large tuning range of optical transmittance through harnessing surface wrinkling–cracking patterns on polydimethylsiloxane (PDMS) films. The ...
