Abstract
An interferometric optical multiplexer 10 for use in optical communication systems and especially for use in optical communication systems employing fibre optical amplifiers is disclosed. The interferometric optical multiplexer has two input ports 12, 14, an output port 16 and an output monitoring port 18. The interaction of the input signals is monitored by a photodetector situated in the monitoring part 18. In conjunction with a feedback circuit 24 wavelength separation of signals input at pods 12, 14 is ensured.
