摘要
An apparatus comprising a signal generator configured to produce a modulation signal, a filter coupled to the signal generator and configured to filter the modulation signal to produce a cancellation signal, and a reflective semiconductor optical amplifier (RSOA) coupled to the signal generator and the filter, wherein the RSOA is configured to generate an optical signal according to a difference between the modulation signal and the cancellation signal and transmit the optical signal towards a partial reflection mirror (PRM).
