摘要： Consistent with the present disclosure optical interleaver and deinterleaver circuits are integrated onto a substrate. The inputs to the interleaver and the outputs of the deinterleaver are each coupled to a corresponding variable optical attenuator (VOA) and optical tap, which are also provided on the substrate. The optical taps supply a portion of the output of each VOA to a corresponding photodetector. A control circuit, which is coupled to the photodetector, in turn, supplies a control signal to each VOA based on the output of the photodetector. Accordingly, optical multiplexing and demultiplexing components, as well as monitoring and power regulating components are provided on the same chip. Such a chip may be compact, relatively inexpensive, and has reduced power consumption compared to optical multiplexer and demultiplexer equipment including discrete components.
