An optical communication system including at a transmitter a semiconductor laser (2) and at a receiver a photodetector (3). Intermediate the transmitter and the receiver is an optical frequency discrimination (4), e.g. a Fabry-Perot resonator. The laser (2) is operated at a substantially constant average power level above the lasing threshold. Superimposed (5) on the substantially constant bias current is a low level modulation signal. The level of modulation of the bias current is sufficient only to cause an effective change in the optical frequency of the laser output without causing the laser oscillations to change from one longitudinal mode to another. The discriminator (4) is tuned to one of the frequencies thus produced. |
