Mode Conversion-Based Crosstalk-Aware Routing, Spectrum and Mode Assignment in Space-Division Multiplexing Elastic Optical Networks

A mode conversion-based crosstalk-aware routing, spectrum and mode assignment (MC-CA RSMA) algorithm is introduced in space-division multiplexing elastic optical networks (SDM-EONs) over few-mode fibers. Simulation results show the MC-CA RSMA algorithm can greatly reduce the impact of inter-mode crosstalk on network performance compared with benchmark algorithms.
