Description

technical field [0001] The invention belongs to the technical field of laser communication, and relates to an integrated electro-optical waveguide modulator with a high-efficiency heat dissipation structure and a preparation method thereof. Background technique [0002] The integrated electro-optic waveguide modulator is the key device to realize the electro-optic modulation in the laser communication system, and the basis of the modulation is the electro-optic effect of the crystal medium. In the electro-optic waveguide modulator, the linear electro-optic effect of the applied electric field causes the refractive index of the optical waveguide medium to change, which in turn causes the phase change of the guided light propagation. Integrated electro-optic waveguide modulators usually use lithium niobate (LiNbO 3 ) crystal as the substrate. However, in practical applications, the temperature change due to the thermoelectric effect of the electro-optical waveguide modulator...
