A Two-Mode (De)Multiplexer Based on Multimode Interferometer Coupler and Y-Junction on InP Substrate

A Two-Mode (De)Multiplexer Based on Multimode Interferometer Coupler and Y-Junction on InP Substrate

A two-mode (de)multiplexer [(DE)MUX] based on a multimode interferometer coupler and a symmetric Y-junction coupler is proposed and demonstrated on an InP substrate. By introducing a phase shifter section with a thickness-detuned core layer, a miniature two-mode (DE)MUX with mode conversion of 100%...
