An LED and a semiconductor laser (or laser LED) work in essentially the same way, that is, light is emitted as electrons and holes combine, with emission wavelength dependent upon the materials used.

Last August, the town of Irondequoit, N.Y., near Rochester, opened its $13 million, 37,800-sf public library. The entry lobby is illuminated by organic light-emitting diode (OLED) fixtures, one of the ...

Nagoya University scientists, in cooperation with Asahi Kasei Corporation, have succeeded in designing a laser diode that emits deep-ultraviolet light, according to research published in the journal ...

Osram Opto Semiconductors has introduced the first compact laser multi-chip package. The PLPM4 450 module can pack up to 20 blue laser chips into a single "butterfly" package for projection ...

WiFi is embedded in our lives today. The term originated about four decades ago (as a marketing ploy, designed to rhyme with the term “Hi-Fi”) and has revolutionized personal communications, internet ...

The world's first automatic and adaptive, dual-mode light-emitting diode (LED)-based optical wireless power transmission ...

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 ...

Lasers are such a fundamental piece of technology today that we hardly notice them. So cheap that they can be given away as toys and so versatile that they make everything from DVD players to corneal ...
