Switching type optical waveguide device based on phase change material and manufacturing method

Abstract

The invention discloses a switching type optical waveguide device based on a phase change material, which comprises a grating structure, an optical film enhancement layer, a ridge structure, a film structure and a substrate structure. The film structure is arranged on the substrate structure, the ridge structure is arranged in the middle of the upper surface of the film structure, the optical film enhancement layer is arranged on the ridge structure, and the grating structure is arranged on the optical film enhancement layer. A mode wave enters one end surface of the optical waveguide device, passes through a waveguide, and is emitted from the other end surface of the optical waveguide device. By means of the mode, a silicon waveguide can be covered with the material to form a composite waveguide structure, optical signal propagation can be switched among different states by switching the phase state of a phase change material, and a time division multiplexing function and a wavelength division multiplexing function are achieved at the same time by means of one structure.
