Anyone who has unlocked a smartphone with facial recognition, used a laser-powered optical mouse or enjoyed high-speed internet has benefited from the work of Kenichi Iga, honorary professor and ...

Surface-emitting semiconductor lasers represent a class of devices in which the optical emission is perpendicular to the semiconductor wafer. This design contrasts with conventional edge-emitting ...

Scientists from Laser Center Hannover ("LZH") and Berlin's Ferdinand-Braun-Institut (FBH) are jointly researching electrically pumped semiconductor disk lasers for ultra-short pulse (USP) generation.

Berkeley engineers have created a new type of semiconductor laser that accomplishes an elusive goal in the field of optics: the ability to maintain a single mode of emitted light while maintaining the ...

Scientists at the University of St. Andrews, UK, say they are leading a "significant breakthrough" in a decades-long challenge to develop compact organic laser technology. While many lasers used for ...

A new, miniature laser source developed by applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Technical University of Vienna (TU Wien) could ...

SANTA CLARA, CA - SEPTEMBER 18: A worker at the displays a strip of a hybrid silicon laser chip at company headquarters September 18, 2006 in Santa Clara, California. Intel announced today that its ...

Welcome to the laser photonics industry, one of the most important and underappreciated ways to invest in the artificial intelligence technology boom. While semiconductor giants tend to grab ...
