Abstract

Weakly-coupled mode division multiplexing (MDM) has been intensively investigated in recent years. In order to be compatible with conventional intensity modulation and direct detection systems, effective solutions to handle degenerate non-circularly-symmetric linearly-polarized (LP) modes (LPlma and LPlmb modes, l ≥ 1) of weakly-coupled few-mode fibers (FMFs) are highly desired. In this paper, a n...
