Optical diodes:
Photo diode:
A photo diode is a p-n junction whose primary function is the detection of light.
It has small window that allows light to strike the PN junction.
A photodiode is always used in reverse bias conditions. Reverse bias only allows a small current to flow through it. this is known as reverse leakage current and is due to the action of the minority carriers. It conducts electric current directly propotional to the amount of light that falls upon it.
