Broadband On-Chip Mode-Division Multiplexer Based on Adiabatic Couplers and Symmetric Y-Junction
The mode-division multiplexer/demultiplexer (MMUX/DeMMUX) is the crucial component for the implementation of mode-division multiplexing (MDM) transmission.We propose an on-chip two-mode MMUX/DeMMUX based on adiabatic couplers.Thanks to the principle of mode evolution, the proposed MMUX read more possesses advantages of broadband operation and high
