摘要：

We have achieved homodyne detection of 4-Gb/s pilot-carrier BPSK optical signals using externalcavity semiconductor lasers synchronized by a linear phaselocked loop. A 215 - 1 PRBS has been transmitted through a short fiber with a receiver sensitivity of - 44.2 dBm or 72 photons/bit. After transmission through 167 km of standard singlemode fiber, the sensitivity is -43.6 dBm or 83 photons/bit. We have employed a balanced PIN/HEMT transimpedance receiver which has a 3-dB bandwidth from 100 kHz to 10.1 GHz and an average equivalent input noise current of [formula omitted]. © 1990 IEEE
