Multi-mode Arrayed Waveguide Grating Demultiplexer with Single-mode Performance

Multi-mode arrayed waveguide grating demultiplexer (MM-AWGD) with single-mode performance is proposed. A hybrid-integrated MM-AWGD consisted of a silica AWG, 3D-waveguide remapping mode multiplexers is demonstrated for coupling to 3-mode few-mode fiber.
