Spun off from a laboratory at Inha University in South Korea, PhotoniSol, a dynamic startup, is leading the charge in silicon photonic integrated devices. The company focuses on commercializing a ...

Members can download this article in PDF format. Relays have enabled low-voltage signals to control high-voltage systems since before the invention of the transistor. With very low on-resistance, the ...

Circuit designers are very familiar with optocouplers, also called optoisolators (and sometimes called optorelays, if configured for on/off mode). They contain a photon-emitting LED with a ...

There is a common misconception that optocouplers will always fail with an “open” circuit when a high-voltage event breaks the device. Although there are many ways that an optocoupler can fail open, ...
