The basis of a solid-state diode laser is, of course, the diode. Laser diodes can have different emission wavelength—most of them have between 405 nm to 808 nm. The diodes usually have TO3, TO5, TO9, ...

And here it is, modelled using LTSpice. It is the same circuit as the classic simple precision rectifier (set to pass the negative half-sine), but with the non-inverting input of the op-amp connected ...

Discover the science behind diodes — the tiny components that control the flow of electricity. Learn how they let current pass in one direction, block it in the other, and power everything from phone ...

A semiconductor-based laser used to generate analog signals or digital pulses for transmission through optical fibers. Both laser diodes and LEDs (light-emitting diodes) are used for this purpose, but ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

Scientists working at the Stanford Institute for Materials and Energy Sciences (SIMES) claim to have created a molecule-sized electronic component just a few nanometers long that conducts electricity ...

Alpha and Omega Semiconductor has announced a family of active diodes which can reduce the 1.2V forward drop of 600V bridge rectifiers. “Both products are self-powered from the AC line and do not ...

A team of physicists at MIPT has offered a new design of a spin diode, placing the device between two kinds of antiferromagnetic materials. By adjusting the orientation of their antiferromagnetic axes ...
