摘要

We report on the fabrication and properties of an optical waveguide in Nd3+-doped phosphate glass.The planar waveguide was obtained by 550-keV proton implantation with a dose of 8.0×1016 ions/cm2.The proton-glass interaction was simulated by the stopping and range of ions in matter (SRIM software).The characteristics of the waveguide including the refractive index profile and the near-field intensity distribution were studied by the reflectivity calculation method and the end-face coupling technique.The optical waveguide demonstrated multi-mode behavior at the wavelength of 632.8 nm.The propagation features of the proton-implanted Nd3+-doped phosphate glass waveguide shows its potential to operate as an integrated photonic device.
