Mode-division multiplexing using few-mode elliptical-core optical fibers (Conference Presentation)

Paper Abstract

Increasing optical fiber communication data speeds with mode division multiplexing, i.e., data transmission over the modes of few mode optical fibers, has received recent interest. As mitigation of mode crosstalk remains a prominent problem, over few kilometer lengths, the canonical solution via coherent detection based multiple-input-multiple-output digital signal processing may be prohibitive. In this presentation, we review the use of few mode elliptical core optical fibers for mode division multiplexing. Due to core ellipticity, an intrinsic reduction of mode crosstalk obviates its mitigation, thereby enabling direct detection based transmission over each mode. Dependence on transmitted mode alignment, optical fiber bending, and polarization mode dispersion, are discussed.
