摘　　要：采用理论仿真分析和实验研究相结合的方法,设计了"基于LiNbO_3晶体电光调制"本科生综合性实验。让学生易理解晶体结构参数设计、工作点选择、调制信号幅度大小等因素对实现电光调制影响;同时,对单轴晶体锥光学干涉图样仿真,使得实验物理过程变得直观形象。该实验启发学生创新性思维,产生良好的教学效果。A comprehensive undergraduate experiment based on LiNbO3 crystal electro-optical modulation was designed by combining theoretical simulation analysis and experimental research.It is easy for students to understand the influence of crystal structure parameter design, working point selection, modulation signal amplitude and other factors on the realization of electro-optical modulation.At the same time, the simulation of the optical interference pattern of the uniaxial crystal cone makes the experimental physical process more intuitive.This experiment inspires students to think creatively and produces good teaching effect.
