Conventional optical amplifiers that use stimulated emission suffer from the generation of excess noise, thus limiting the performance in many applications. The phase-sensitive optical
An ''Optical Receiver'' is a device that detects and converts the light received from a transmitter into an electrical signal. It consists of a photodetector and an amplifier, which work together to minimize
