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 ...

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, ...

If you love the lasers of science fiction, rejoice because the future will be full of them, according to Nobel laureate Shuji Nakamura, co-inventor of the blue light-emitting diode (LED). The power ...

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 ...

High-power semiconductor laser diodes represent a critical technology underpinning modern industrial, medical, and telecommunications applications. These devices convert electrical energy into ...

Laser diodes are semiconductors that generate light and amplify it using repeated reflection or "optical feedback." Once the light has achieved desirable optical gain, laser diodes release it as ...
