In this paper, we propose a thermo-optic reconfigurable three-mode (de)multiplexer based on an asymmetrical horizontal three-waveguide directional coupler that includes two identical single-mode waveguides and a three-mode waveguide. Over the whole wavelength range of 1540-1560 nm, and for the TE (TM) polarization, our typical fabricated device with polymer material shows coupling efficiencies as high as 94% (93%) and 93% (92%) for the mode conversions of - and - , with the heating powers of 53.57 mW and 71.19 mW, respectively. Our proposed device can be employed in the fields of reconfigurable mode-division multiplexing systems.
在本文中，我们提出了一种基于非对称水平三波导定向耦合器的热光可重构三模（解）复用器，该耦合器包括两个相同的单模波导和一个三模波导。在1540 - 1560 nm的整个波长范围内，对于TE（TM）偏振，我们用聚合物材料典型制备的器件在模式转换 和 时，耦合效率分别高达94%（93%）和93%（92%），加热功率分别为53.57 mW和71.19 mW。我们提出的器件可应用于可重构模分复用系统领域。
