This paper proposes a new structure of periodic photonic crystal based on the hybrid integration of silicon-based waveguides and phase change materials, which is used to construct optical switch device. This device innovatively embeds a one-dimensional photonic crystal structure in a silicon waveguide and fills its nanoscale circular holes with germanium antimony selenide tellurium (Ge-Sb-Se-Te, GSST) phase change material. By regulating the crystalline phase transition of GSST materials, dynamic control of dual-mode optical transmission can be achieved. Theoretical analysis shows that the synergistic effect of silicon waveguides and phase change materials can significantly improve the response speed of silicon-based optoelectronic devices and reduce power consumption. The three-dimensional finite difference time domain (FDTD) method was used to systematically simulate and optimize the optoelectronic characteristics of the device. The results showed that, when GSST is in the crystalline state, the normalized output powers of TE and TM modes are
