Homodyne receiver prototype with time-switching phase diversity and feedforward analog processing.
A differential phase shift keying homodyne optical receiver is experimentally demonstrated based on time-switching phase diversity, without the need for a 90 degrees optical hybrid. It achieves high tolerance to phase noise and feasible implementation with off-the-shelf electrical and optical components.
