Some property analyses on optical waveguide of Nd doped crystal Nd x Y 1-x A1 3(BO 3) 4 and Nd∶MgO∶LiNbO 3 are made in this paper, followed by introduction of the methods of experimentation and theoretical calculation for the planar optical waveguides. The refractive index profiles of the optical waveguides are analyzed. The above work offers useful information for study on new type materials for optical communications.展开更多

After poling of the film, the refractive indices n t and n n, that is the in-film-plane and the normal-to-film-plane refractive indices at 633 nm and the thickness d were determined using the quasi-waveguide m -line method. The results of measurement and calculation are: n t=1.657 3±0.001 7, n n=1.627 8±0.001 9, and d =1.427 8±0.003 1 μm.展开更多
