摘　　要：铌酸锂晶体具有良好的光声和电光性质,因而基于铌酸锂的集成光学器件已引起人们的广泛关注。质子交换法是一种制备铌酸锂光波导的重要方法。质子交换铌酸锂光波导具有制作工艺简单,折射率增量大,抗光折变能力强及可实现单偏振激励等特点。本文对质子交换铌酸锂光波导的制作工艺、波导特性及其应用进行了讨论,并指出目前应加强质子交换光波导、质子交换生长动力学和交换工艺的研究。Integrated optical devices based on lithium niobate(LiNbO3)crystals have started to arouse interest due to their excellent acousto-optical and electro-optical properties.Proton-exchanged method is an important way to fabricate the LiNbO3 optical waveguides.Proton-exchanged LiNbO3 optical waveguides(H∶LiNbO3)are characterized by simple fabrication process,large surface refractive index increasement,high photorefractive damage resistance and single extraordinary polarization supported.The fabrication process and waveguide properties of H∶LiNbO3 and its applications are discussed in detail.The authors also point out that the research on the growth dynamics of proton-exchanged waveguides and the fabrication process should be strengthened.
