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 ...
With superconducting diodes, scholars advance work toward ultra-efficient quantum electronic devices
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 ...
How does a varactor diode work? To form the PN junction that makes a diode, half the piece is doped with a trace amount of “donor atoms” that have one more electron than the intrinsic stuff to make ...
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.
