A semiconductor-based laser used to generate analog signals or digital pulses for transmission through optical fibers. Both laser diodes and LEDs (light-emitting diodes) are used for this purpose, but ...

When we think about the onward march of automotive technology, headlights aren’t usually the first thing that come to mind. Engines, fuel efficiency, and the switch to electric power are all more ...

The miniature laser diode emits more intense light than those currently used. A new laser device created at the University of Central Florida could make high-speed computing faster and more reliable, ...

Do Laser Caps Work for Hair Growth? If you’ve ever searched for hair loss treatments, you may have stumbled across something called laser hair growth caps. Less invasive than a hair transplant and ...

ROHM’s RLD8BQAB3 1-kW, 905-nm, 8-diode laser array comes in a 5.6- × 3.3-mm SMD package. The spectral output is well-suited to ADAS applications for high-speed vehicles, providing scene illumination ...

In 1989 Shuji Nakamura was one of many scientists who were trying to develop a blue laser-diode. However, unlike his contemporaries, Nakamura was working on a semiconductor called gallium nitride.
