Lasers emit a single precise wavelength (630 nanometers); LEDs emit a broader range clustered around a target wavelength, ...

Needless to say, we’re fascinated by LEDs, laser diodes, and other blinkies. Although we can get just about any light emitting thing, the data sheets aren’t always accurate or available. For his ...

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 ...

Belgian research lab Imec is claiming to have created a metal halide perovskite LED stack that emits 1,000x more light “than state-of-the-art OLEDs”, it said. With the assistance of an external laser, ...

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.

Laser is of prime importance in Optical memories, Fiber optic communications, Military applications, Surgical procedures, CD players, Printers etc. Various forms of lasers like Gallium Arsenide laser, ...

Called RLD90QZW8, “original technology allows Rohm to reduce the temperature dependence of the laser wavelength to just Δ11.6nm – 0.10nm/°C”, said the company. “This makes it possible to narrow the ...

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 ...

With optoacoustics having "come of age" as an imaging technique, the hottest topics in the sector now revolve around development of effective clinical systems for human applications. Suitable laser ...

Optical interconnects have attracted much research attention in recent years owing to potential performance and power-consumption improvements over traditional electrical connectivity. A complete ...

Efficient 1.5 W CW and 9 mJ quasi-CW TEM00 mode operation of a compact diode-laser-pumped 2.94 µm Er:YAG laser Sheaumann has developed the first commercially available diode-laser-pumped continuously ...
