Photodetectors

A Photodetector is form of a light-weight sensor that converts light energy into electrical voltage or current. Photodiode is a type of semiconductor device with a PN junction. Between the positive (p) and negative (n) doped layers, a depletion layer is formed. Incident light causes the device to generate electric current as result of this excitation.These devices are also called photo sensors or light detectors. Photo diodes operate in reverse bias condition i.e. the p-side is biased with a lower potential than the n-side. Photodiodes are typically made with Silicon, Germanium, Indium, Gallium Arsenide Phosphide and Indium Gallium Arsenide.

Applications of Photodiode

  • Optical Communication System
