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 ...

Electricity doesn’t just flow freely in every direction—it needs control. That control comes from a tiny but powerful component: the diode. In this video, you’ll learn how diodes work, why they allow ...

PROVIDENCE, R.I. [Brown University] — Superconductors — materials that conduct electricity with zero loss of energy — have been well-understood since the development of what’s called the BCS theory in ...

With a tuning range from 0.5V to 2.5V, the ZV950 series of hyperabrupt varactor diodes meets the requirements of 3V frequency control and filtering systems. The diodes are reported to be characterized ...

The diode is one of the most commonly adopted and simply made elementary component in semiconductor technology. It’s been the basic starting brick for the construction of all electronic technology, ...

Our expert, award-winning staff selects the products we cover and rigorously researches and tests our top picks. If you buy through our links, we may get a commission. James has been writing about ...

Among passive electronic components, the fuse and diode are well known, well understood, widely used, and essential to many circuits and systems. Still, each has inherent shortcomings that make them ...

In 1989 Shuji Nakamura was one of many scientists who were trying to develop a blue laser-diode. However, unlike his contemporaries, Nakamura was working on a semiconductor called gallium nitride.
