Abstract :
Multifunctional properties of an InGaAsP semiconductor laser amplifier have been evaluated. A bit error rate of 10-9 at 100 Mb/s was obtained using the amplifier as a detector at a received optical power of -27 dBm with simultaneous cavity gain of 16 dB. The bandwidth of the amplifier detector was 300 MHz and the maximum responsivity was 30 V/W. The amplifier had a maximum gain of 29 dB and a very large optical on/off ratio of 50 dB. When the amplifier was used as a switch the cavity gain was 19 dB and the extinction ratio was 22 dB
