分析了单齿形和T形波导结构的特性。提出了一种基于双矩形齿T形波导的纳米等离子体波长解复用器，并用完全匹配层吸收边界条件下的时域有限差分方法进行了数值模拟。结果表明，这种新型光波导结构可以实现通信波长的波分复用功能。解复用波长可以通过其中一颗牙齿的深度线性且独立地控制。
Characteristics of single tooth-shaped and T-shaped waveguide structures are analyzed. A nanometeric plasmonic wavelength demultiplexer based on a T-shaped waveguide consisting of double rectangular teeth is proposed and numerically simulated by using the finite difference time domain method with a perfectly matched layer absorbing boundary condition. It is found that the new waveguide structure can realize a wavelength demultiplexing function at telecommunication wavelengths. The demultiplexing wavelength can be linearly and independently controlled through the depth of one of the teeth.
