The refractive index profile at either 632.8-nm wavelength or 1539-nm wavelength was optical barrier type in the proton-implanted Nd：CLNGG crystal optical waveguide, which was calculated by using the reflectivity calculation method. The near-field light intensity distributions were also simulated by the finite-difference beam propagation method in the visible and nearinfrared bands.展开更多

The optical modes as well as the effective refractive indices are measured by the prism coupling method. The refractive index distribution in the fluoride lead silicate glass waveguide is simulated by the reflectivity calculation method(RCM). The light intensity profile and the energy losses are calculated by the finite-difference beam propagation method(FD-BPM) and the program of stopping and range of ions in matter(SRIM), respectively. The propagation properties indicate that the C^(2+) ion-implanted fluoride lead silicate glass waveguide is a candidate for fabricating optical devices.展开更多
