讨论了用锁相1.5 μ m外腔半导体激光器对1Gb/s导频载波（BPSK）光信号进行零差检测的方法。在2/sup 15/-1伪随机二进制序列（PRBS）的209 km光纤传输之后，测量的接收机灵敏度为52.2 dBm或46个光子/比特。给出了数据与锁相串扰的实验证据，该串扰可能限制导频载波PSK零差系统中可用的线宽与比特率之比。<<ETX>>
Homodyne detection of 1 Gb/s pilot-carrier (BPSK) optical signals using phase-locked 1.5 mu m external-cavity semiconductor lasers is discussed. After 209 km fiber transmission of a 2/sup 15/-1 pseudorandom binary sequence (PRBS), the measured receiver sensitivity is 52.2 dBm or 46 photons/bit. Experimental evidence of the data-to-phase-lock crosstalk that potentially limits the usable ratio of linewidth to bit rate in pilot-carrier PSK homodyne systems is presented.<<ETX>>
