Abstract
This chapter reviews optical detectors and receivers for optical communication systems. An optical receiver includes both the optical detectors, or photodetectors, and various electronic circuits such as amplifiers or clock recovery circuits. It discusses semiconductor devices such as PIN photodiodes, avalanche photodiodes (APD), photodiode arrays, Schottky-Barrier photodiodes, metal-semiconductor-metal (MSM) detectors, resonant-cavity photodetectors, and interferometric devices. APDs are used in high sensitivity applications, MSM photoconductive detectors are sometimes used because of their ease of fabrication, and Schottky-barrier photodiodes are used for high-speed applications. The chapter discusses optical receiver circuits. It concludes with a discussion of noise sources and their impact on the detection electronics. Detectors are an integral part of all fiber optic communication systems. They convert a received optical signal into an electrical signal, demodulating the optical signal that was modulated at the transmitter.
