Shot noise in optical receivers includes

A fundamental limit to the optical intensity noise as observed in many situations (e. In electronics, shot noise originates from the discrete nature of electric charge. Radi-ation falling on the element causes the air temperature inside the chamber to rise and hence the air pressure to increase. This pressure change is then detected in a number of ways, including the use of a flexible. Optical receivers convert incident optical power P in into electric current through a photodiode. [pdf]
