摘　　要：针对分段电极结构的集成光学电场传感器,分析了电场探测系统的灵敏度,得到了影响灵敏度的各个参数,并做了优化,经过优化的这种电场探测系统的极限灵敏度可达到19.4dBμV/m。模型分析所得该传感器的探测灵敏度为87.3dBμV/m,与实验得到的90.0dBμV/m基本一致。The sensitivity of the integrated eledetric-field sensing system,which is based on the electric field sensor with the segmented electrodes,is analyzed. The parameters that impact the sensitivity of the sensing system are obtained and optimized. The limit sensitivity of the sensing system is given. The experimental result is 87.3 dBμV/m which is in accord with the theoretical prediction of 90.0 dBμV/m.
