Versatile Two-Mode ODFT-Based Labeling in Mode-Multiplexed Optical Packet Switching

Abstract

A single-mode labeling approach is proposed for a mode-multiplexed OPS system, and the corresponding detection performances are evaluated as a function of the received power. We introduce the mode dimension to increase the number of labels that can be generated and processed by a single multiport E/D, and we analyze configurations with reduced intra-mode crosstalk. We show that the label error rate is significantly influenced by inter-mode crosstalk, being TE10 labels more susceptible to crosstalk from adjacent ports, than TE00 labels.
