Optical Noise
Optical systems can be subject to shot noise and optical noise, in addition to the standard thermal noise. These require somewhat different models and performance expressions. Receiver
Optical Receivers | part of Fiber-Optic Communication Systems
The design of an optical receiver depends on the modulation format used by the transmitter. The chapter deals with various noise sources that limit the signal‐to‐noise ratio in optical receivers, and also
Optical Receiver Sensitivity Evaluation in Presence of Noise in Digital
The optical receiver adds two types of noise namely thermal noise and shot noise. Since optical amplifiers are based on the principle of stimulated emission, its main contribution to noise is ASE noise.

This application note provides an in-depth analysis of the complete receiver optical sensitivity and the potential power penalties related to the accumulation of random noise and inter-symbol interference
Optical Receiver Noise
The objective of this tutorial is to review the noise mechanisms and then discuss the signal-to-noise ratio (SNR) in optical receivers. The p-i-n and APD receivers are considered in separate subsections, as
Lecture 15: Receiver Design
At the receiver, there is noise on the signal arriving at the input and and after detection added to that is noise that is injected at various stages of the receiver
