Name the optoelectronic device used for detecting optical signal and mentioned the biasing in which it is operated . Drow its I-V characteristics

Dear Student ,

The correct answer is - Photodiode.
 

Optoelectronic devices are semiconductor devices in which the carriers are generated by protons via photo excitation.

 

A photodiode is a special type of junction diode that is used for detecting optical signals. It is a reverse biased p – n junction that is made from photosensitive material. The current in the photodiode changes with a change in the light intensity (I) when a reverse bias is applied.
