As the core unit in the communication field and microwave technology, electro-optical modulators should have large modulation bandwidth and high modulation efficiency in order to meet the needs of ultra-wideband, large dynamic microwave optical transmission、microwave photonic signal processing applications、high performance and so on. In this paper, the structure of the silicon-organic composite Mach-Zehnder modulator is designed and simulated, and electro-optic organic polymers are filled in the slot waveguide, which gives full play to the large-scale integration of silicon and the advantages of organic polymer materials with high electro-optic coefficients. We obtained the data: the transmission loss was 2.2322dB/mm through the design and simulation optimization of the slot waveguide structure. At the same time, we optimized to obtain the coupling of the Strip-to-Slot mode converter for the multimode interference (MMI) waveguide mode conversion structure. The coupling efficiency was 0.9324. It can improve the modulation efficiency of electro-optic modulators, which has certain reference significance for the design of electro-optic modulators.
