Description
Summary: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 <inline-formula><tex-math notation="LaTeX">${E_{00}}$</tex-math></inline-formula>, <inline-formula><tex-math notation="LaTeX">${E_{01}}$</tex-math></inline-formula>, <inline-formula><tex-math notation="LaTeX">${E_{10}}$</tex-math></inline-formula> and <inline-formula><tex-math notation="LaTeX">${E_{11}}$</tex-math></inline-formula> 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 &#x03BC;s (rise) and 103.4 &#x03BC;s (down), and that of 2 and 4 graphene heater mode switch calculated are 17.3 &#x03BC;s (rise) and 87.9 &#x03BC;s (down). The proposed model can be used in the field of low power consumption mode division and multiplexer of three-dimensional integrated.
