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.

Serving as CW light sources in fiber optic transmission systems that employ external modulators, the NX8570 and NX8571 series DFB laser diode modules provide eight channels, tunable with 50 GHz ...

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 ...

The human eye is as comfortable with white light generated by diode lasers as with that produced by increasingly popular light-emitting diodes, according to new tests. Both technologies pass ...

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 ...

Third-Generation Combined Power Modules (CPM III) Use Single Emitter Diodes to Deliver Over 20,000 Hours MTTF Operation New from Alfalight Inc is the AC3-808B and AC3-808BW series of high-brightness ...

Color digital laser and light-emitting diode printers are very similar. Both can print your business documents relatively quickly by melting toner to the paper, and both use a photosensitive drum. The ...

As a laser diode nears the end of life, imminent failure is signalled by an increase in current being drawn from its drive circuitry. When the current draw is 120% of its original value, the laser ...
