Abstract
Although there are many types of photodetectors, only three are commonly considered for the direct detection of digital signals in optical communications: the photoconductor, the p-i-n diode, and the avalanche photodiode. The advantages and disadvantages of each type are discussed. The problems of speed, security, and noise are stressed.Keywords
