摘　　要：在可见光域（６３２．８ｎｍ光波段）研制出钛扩散铌酸锂质子交换光波导偏振器。同时，给出波导偏振器参数测试装置。在理论上，利用物理光学和波导色散理论分析与计算了这种偏振器的消光比，分析了影响器件性能的各种因素。Optical waveguide polarizers in visible light region632.8 nm have been fabricated in LiNbO 3 by proton exchange technology. Measuring setup are introduced. The polarization extinction ratio are calculated and analysed with physical optics and waveguide optics. The experimental results cincide well with theoretically calculated data.
