Sensitivity of direct-detection lightwave receivers using optical preamplifiers

Abstract

A simple technique for analyzing the sensitivity and bit-error-rate (BER) performance of direct-detection lightwave receivers using optical preamplifiers is presented. The analysis provides closed-form expressions for the system performance and includes the impact of phase noise. For a negligible linewidth, the theory predicts an average signal energy of 42… (More)
