Abstract
The temperature distribution of the heat waveguide optical switch with different cladding materials is simulated on Fourier heat conduction theory and non-Fourier heat conduction theory, discussing effect of the cladding materials on the power consumption and the response speed of the device. The main conclusions as follows: (1)The response speed of waveguide optical switch with silica as cladding is faster than that with PMMA as cladding. (2)Thermal relaxation time has significant influence on the temperature of the core layer: the variation of optical switch core layer temperature gets bigger with the increase of material thermal relaxation time.
