Semiconductor Lasers Power Up

Facebook Twitter LinkedIn Email Comments

With increasing power, brightness and new wavelengths on the horizon, semiconductor lasers may one day be as ubiquitous as LEDs.

HANK HOGAN, CONTRIBUTING EDITOR, [email protected]

Improvements to semiconductor lasers promise big changes, from increases in power to expanded wavelengths. Other innovations could mean faster data rates for a bandwidth-hungry world. And then there are self-driving cars. Equipped with lidar, autonomous vehicles are likely to spark demand for improved semiconductor lasers. Finally, researchers are investigating semiconductor lasers that can be built to output any desired wavelength, enabling new uses. For some applications, what’s important is not just increasing the power that a semiconductor laser can deliver. Instead the...Read full article
