| 摘 要： | 一、引言 目前,LiNbO_3是集成光学系统中使用较为广泛的衬底材料。自从Zhong等人首次报道了掺MgO的LiNbO_3晶体具有抗光损伤效应以来,MgO:LiNbO_3晶体在集成光学系统中得到了越来越广泛的应用。而质子交换MgO:LiNbO_3波导具有比纯LiNbO_3质子交换波导高的抗光损伤能力。把具有较好激光性能的钕离子掺入LiNbO_3中就能制成波导激光器。

| Abstract: | Nd:MgO:LiNbO3 waveguides have been fabricated by proton-exchange method. Employing the prism-coupling, we measured the effective refractive indices of the waveguides to obtain effective index profiles and diffusion coefficient. Infrared absorption spectra of the waveguides have been measured. The results indicate that the properties of the waveguides are similar to those of the proton-exchange MgO:LiNbO3 waveguides. |
