Diode lasers (or laser diodes) are semiconductor lasers which use electrical power as an energy source and doped p-n junctions as a gain medium. As discussed in the Lasers Selection Guide, all lasers ...

Current limiting diodes (CLD) regulate current over a wide voltage range. CLDs are used in many applications. Some examples include waveform generators, battery chargers, and timing circuits. CLDs are ...

The evolution of diode laser price and performance is rapidly opening new markets. In this article, the technology consulting firm IDTechEx demonstrate how advances in semiconductor laser technology ...

Photonics researchers at the National Physical Laboratory (NPL) have achieved the extra-ordinary by creating a diode consisting of light that can be used, for the first time, in miniaturised photonic ...

A diode is a device that allows current to flow in one direction but not in the other. This ability makes diodes useful in many applications, including converting AC to DC, regulating voltages, and ...

We might tend to take the word “diode” for granted if we’re thinking of a “diode” as just a two-lead or two-terminal device that gets used in this or that place for this or that purpose. It can become ...
