Abstract: A high-speed low-voltage electro-optic modulator based on a lithium niobate-silicon wafer. The silicon wafer is located above a lithium niobate wafer (8). A lithium niobate-silicon hybrid waveguide is formed by etching a silicon waveguide layer (9). Changing the structure of a silicon waveguide allows light waves to have different energy distribution in the lithium niobate-silicon hybrid waveguide. When the silicon waveguide has more energy distribution, it is suitable for realizing a compact demultiplexing function, a multiplexing function and a thermo-optic modulation function; when the lithium niobate waveguide has a higher energy distribution, it is suitable for realizing a high-speed low-voltage electro-optic modulation function. The advantages of a lithium niobate and a silicon material platform are exerted, so as to obtain an electro-optic modulator suitable for high-speed low-voltage.
