  • Abstract Coherent lightwave communications systems are approaching a limit where the error rates and channel capacities are limited by the quantum properties of light. This is often referred to as the shot-noise limit. If ideal laser light is used in the system, there is no way to avoid this limit. However, a novel idea to improve the receiver sensitivity of the coherent detection system is proposed in this master thesis. This novel idea is fulfilled through some numerical simulations. The theoretical study of quantum squeezing is explained, and the simulation method uses two algorithms to compose. The details of these two algorithms, phase rotation and phase sensitive amplification, will be explained. There are two simulations demonstrated in this master thesis, intensity modulation direct detection (IM-DD) and binary phase shift keying (BPSK). The results for these two simulations are demonstrated after the explanations of both simulations.
