摘　　要：文中提出新型的能提高调制器调制特性的光纤型行波调制器。利用有限元法(FEM)准确地分析它的电场分布,得到不同结构尺寸下的微波有效折射率和特性阻抗。从而为优化设计光纤型行波调制器提供理论基础。In this paper, a novel optical fiber type traveling- wave modulator with high modulating characteristics is introduced. In the paper, the electric field of modulator is analysed by FEM accurately. For different structure dimensions of CPW electrodes, the microwave effective refractive index and characteristic impedance are gotten. And the analysis results provide theory basis for the optimal designing of optical fiber type traveling- wave modulator.
