Experimental investigation of channel crosstalk in a time-switched phase-diversity optical homodyne receiver.
Theoretical and experimental study of channel crosstalk effects in time-switched phase-diversity optical homodyne reception is presented, focused toward ultradense WDM passive optical networks. This receiver achieves ultralow channel spacing of 3 GHz per 1 dB power penalty at 1 Gbit/s and feasible implementation.
