We present a polymer thermo-optic mode switch based on the structure of two vertical Mach-Zehnder interferometers (MZIs). It can achieve a rapid switch between ${E_{00}}$, ${E_{01}}$, ${E_{10}}$ and ${E_{11}}$ with the different heaters turning on. In our simulation, we compare two structures (the metal top electrode and the graphene electrode). The Finite element method (FEM) is used to simulate the parameters of the graphene electrode device. The power consumption of 1 and 3 heaters is 1.72 mW, and that of 2 and 4 heaters is 1.85 mW. In addition, the response speeds of the 1 and 3 graphene heater mode switch calculated are 36.9 μs (rise) and 103.4 μs (down), and that of 2 and 4 graphene heater mode switch calculated are 17.3 μs (rise) and 87.9 μs (down). The proposed model can be used in the field of low power consumption mode division and multiplexer of three-dimensional integrated.

基于三维聚合物MZ干涉仪的低功耗模式切换

我们提出了一种基于两个垂直马赫-曾德干涉仪 (MZI) 结构的聚合物热光模式开关。它可以实现之间的快速切换${E_{00}}$, ${E_{01}}$, ${E_{10}}$ 和 ${E_{11}}$随着不同的加热器打开。在我们的模拟中，我们比较了两种结构（金属顶电极和石墨烯电极）。有限元法（FEM）用于模拟石墨烯电极器件的参数。1和3加热器的功耗为1.72 mW，2和4加热器的功耗为1.85 mW。此外，计算出的1和3石墨烯加热器模式开关的响应速度分别为36.9 μs（上升）和103.4 μs（下降），2和4石墨烯加热器模式开关计算的响应速度分别为17.3 μs（上升）和87.9 μs（下）。该模型可用于三维集成的低功耗模分复用器领域。
