Abstract

A simple technique for analyzing the sensitivity and bit-error rate performance of direct- detection lightwave receivers using optical preamplifiers is presented. Our analysis provides closed-form expressions for the system performance, and includes the impact of phase noise. For zero (negligible) linewidth, our theory predicts an average signal energy of 42.3 photons/bit at BER equals 10-9. In comparison, at BER equals 10-9 Ref. 1 predicts an average signal energy of 38 photons/bit.
