Alternative design for blue-emitting laser diodes developed

Alternative design for blue-emitting laser diodes developed

Aug 10, 2017: Researchers at the University of California, Santa Barbara (UCSB) have developed an alternative design of blue-emitting laser that has a current aperture formed by photoelectrochemical etching. Ludovico Megalini, spokesman for the UCSB team, said that this work shows that selective lateral etching, in a controllable way, is possible in a complex nitride-based structure, such as a laser ...

Laser Li-Fi is ten-times faster than LED Li-Fi

Laser Li-Fi is ten-times faster than LED Li-Fi

By BizLED Bureau Dec 23, 2016: Li-Fi technology that uses LED lighting instead of radio waves to transmit data, will now use laser-based lighting, that will transmit data rate ten times faster. Laser-based Li-Fi will have better light output than LED. The project is being conducted by Harald Haas, chairman of mobile communications at the University of Edinburgh. He is ...
