Question

Name the optoelectronic devices used for detecting optical Signals and mention the biasing in which it is operated draw its 1 to 5 characteristics

Answer 1

An Optoelectronic device is a kind of a semiconductor device in which the photons generate the carriers by photoexcitation.

A Photodiode is a kind of optoelectronic device which is used for detecting optical signals. Photodetectors are types of photodiodes or optoelectronic devices that help in detection of optical signals, to measure the illumination signals, etc. LED diodes are also optoelectronic devices that convert electrical energy into the light energy.

These optoelectronic devices work on the p-n junction or the reverse biased p-n junction systems. They are usually made using photosensitive materials.
