On-chip simultaneous mode and wavelength division-multiplexing (MWDM) is proposed using a tapered directional coupler and multimode interference (MMI) waveguide. A simulation is performed on the two different MWDM architectures, in which, two waveguide eigenmodes and two wavelength channels (1310/1550nm) are multiplexed. One of the proposed devices is compact (6μm x 100μm) and exhibits insertion loss as low as 1.2dB with a cross-talk of (-18dB).
提出了一种利用锥形定向耦合器和多模干涉（MMI）波导的片上同时模式和波分复用（MWDM）技术。对两种不同的MWDM架构进行了仿真，其中，两个波导本征模式和两个波长通道（1310/1550nm）被复用。所提出的器件之一结构紧凑（6μm×100μm），插入损耗低至1.2dB，串扰为（-18dB）。
