SUMMARY
To be used for optical coherent detection, including QPSK receiver, Optoplex’s six-port 90° Optical Hybrid mixes the incoming signal with the reference signal to generate four quadratural states in the complex-field space. The optical hybrid then delivers the four light signals to two pairs of balanced detectors. See the block diagram below for the application of 90° Optical Hybrid in a coherent receiver.
