A group of scientists led by the US Department of Energy's National Renewable Energy Laboratory (NREL) has designed a monocrystalline mini solar panel that can convert laser light into electricity.

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 ...

A team at Harvard and Technical University of Vienna have invented a new tunable laser that uses a series of rings to smoothly emit many light wavelengths from a single chip. The laser could replace ...
