This present chapter is devoted to the description of the noise processes relevant to microwave photonics, therefore spanning electrical and optical domains. It provides a focused treatment of the topic as it pertains to microwave photonics. The treatment in the chapter begins with an introduction to basic noise concepts and how they are tied to the RF performance. Individual noise components are then treated separately starting with fundamental sources: thermal and shot noise. Additional noise arising from basic components in a fiber optic link is analyzed including excess noise from lasers, optical amplifiers, and photodiodes. The chapter discusses the concept of thermal noise in order to define the RF noise factor. Optical amplifiers are often used in microwave photonic links. They can be employed in short and long links alike to increase or maintain signal power. The chapter describes the treatment of excess amplitude noise due to the ionization process.
