In-service method of path length alignment in SDM systems with self-homodyne detection

An in-service path length alignment subsystem for phase noise cancellation in self-homodyne coherent detection systems is proposed and demonstrated for spatial division multiplexing multi-core fiber links. Sub-centimeter resolution is demonstrated with penalties below 0.5dB.
