A Weakly-Coupled Few-Mode Optical Fiber With a Graded Concave High-Index-Ring

A Weakly-Coupled Few-Mode Optical Fiber With a Graded Concave High-Index-Ring

This paper proposes a novel refractive index profile design based on few-mode fibers (FMFs) which can support 4 linear polarization (LP) modes. We first present a FMF whose core is dually assisted by a nano-hole (NH) and a high-index-ring (HIR), and then substitute the dual assistance by an innovati...
