Author Affiliations +
Optical signal processing using coherent optical frequency combs could have various potential applications for optical communications. In the beginning, an approach to achieve a tunable optical high-order QAM generation based on multichannel aggregation is discussed. Then, an all-optical pilot-tone based self-homodyne-detection scheme is demonstrated under two scenarios: (i) multiple WDM channels with sufficient power of pilot tones, and (ii) a single channel with a low-power pilot tone. Finally, a fragmented bandwidth allocation enabled by reconfigurable channel slicing and stitching is presented, in which a single optical channel could be redistributed into fragmented frequency slots and ultimately recovered at the receiver side.
