• PIN photodiodes: High speed, low gain, low noise, ideal for most systems.
• Avalanche photodiodes (APDs): Internal gain (multiplication factor M), excess noise factor, higher sensitivity but temperature sensitivity and bias complexity.

Gowar divides the exploration of an optical communication system into three primary building blocks, matching the classic communication model: the transmitter, the channel, and the receiver. The Optical Transmitter: PIN photodiodes : High speed, low gain, low
