At the destination, the optical signal must be converted back into an electrical signal. Gowar thoroughly investigates semiconductor photodiode detectors, specifically PIN photodiodes Avalanche Photodiodes (APDs)
Optical communication systems use light to transmit information through optical fibers or free space. These systems consist of three main components: a transmitter, a channel, and a receiver. The transmitter converts electrical signals into optical signals, which are then transmitted through the channel, typically an optical fiber. The receiver converts the optical signals back into electrical signals, allowing the information to be retrieved. optical communication system by john gowar pdf
