Coherent detection only by 2-D photodetector array: A discreteness-aware phase retrieval approach
Optical Fiber Communication Conference, 2019•opg.optica.org
A simple and spatially-flexible coherent receiver without local lights, optical hybrids, or
spatial de-multiplexers is experimentally demonstrated; 2× 10-Gbaud SDM QPSK signals
were detected only by 2-D arrayed photodetectors based on a novel phase-retrieving
technique.
spatial de-multiplexers is experimentally demonstrated; 2× 10-Gbaud SDM QPSK signals
