Abstract: A system for processing optical signals comprising a reference optical signal transmission structure configured to receive an optical signal at a first input and to provide the optical signal at a first output to a photodetector. A delay optical signal transmission structure configured to receive the optical signal at a second input and to provide a delayed optical signal at a second output to the photodetector. A signal processor configured to receive a first electric signal corresponding to the optical signal and a second electric signal corresponding to the delayed optical signal and to generate an output as a function of the first electric signal and the second electric signal.
