Photodiode Modes of operation, working principle and Applications

Photodiode image

Photodiode is a special kind of diode convert light energy into current or voltage. It can be used to detect the presence or absence of minute quantities of light and can be calibrated very accurate for measurements. In our previous articles, we explain about LED diode, Zener Diode, P-n junction diode etc. Here we are going to explain Photodiode operation, working principle, modes etc in detail. These may be either exposed or packaged with an¬†optical fiber¬†connection or window to allow light to reach the sensitive part of the device. It may contain in-built lenses, optical filters and frequently uses photo Read More …
