A novel mode-division (de)multiplexer with degenerate modes output for MIMO-FREE applications

open access: yesFrontiers in Physics, 2022
In this study, we propose a novel three-dimensional architecture mode (de)multiplexer with degenerate modes output using a pure silica FMF ring core transmission channel, which solves the problem caused by random mode rotation and can be used in multiple-
