Avalanche photodiodes (APDs) represent a cornerstone of modern photodetection technologies, employing the impact ionisation process to multiply weak optical signals and thereby enhance sensitivity.
CMC Electronics' 276-339767-VAR is a pigtailed InGaAs APD Series available in 30 µm (single mode fiber, SMF) and 80 µm (multimode fiber, MMF) active area variants, both with very high operating gain ...
[Hans Rosenberg] has a new video talking about a nasty side effect of using resistors: noise. If you watch the video below, you’ll learn that there are two sources of resistor noise: Johnson noise, ...
