Engineers are turning what used to be a bulky optics bench into something that fits on the tip of a finger, and the latest photonic chips go a step further by splitting a single laser into a ...

Unlike fictional laser swords, real laser beams do not interact with each other when they cross -- unless the beams meet within a suitable material allowing for nonlinear light-matter interaction. In ...

UPTON, NY—Lasers are intense beams of colored light. Depending on their color and other properties, they can scan your groceries, cut through metal, eradicate tumors, and even trigger nuclear fusion.

Measuring conditions in volatile clouds of superheated gases known as plasmas is central to pursuing greater scientific ...

The photonic based technology boom of the late 1990s was driven by the need to replace expensive, lag-prone and limited satellite telecom links. These links were based on high frequency radio waves ...
