  • Abstract
    A receiver for PSK optical signals is analysed. The demodulation is performed directly by launching the received signal into an injection-locked semiconductor laser. The locked laser converts phase modulation into current modulation, which is sent to the data detection system after some signal processing. The signal to noise ratio of the receiver can reach 4599 phi 2 for a 100 Mbit/s rate and a 100 kHz emitter linewidth, where phi is the phase deviation of the modulator.
