Abstract

Abstract: Planar waveguides in magneto-optical glasses (Tb 3+ -doped aluminum borosilicate glasses) have been produced by a 550-keV proton implantation at a dose of 4.0×10 16 ions/cm 2 for the first time to our knowledge. After annealing at 260 °C for 1.0 h, the dark-mode spectra and near-field intensity distributions are measured by the prism-coupling and end-face coupling methods. The damage profile, refractive index distribution and light propagation mode of the planar waveguide are numerically calculated by SRIM 2010, RCM and FD-BPM, respectively. The effects of implantation on the structural and optical properties are investigated by Raman and absorption spectra. It suggests that the proton-implanted Tb 3+ -doped aluminum borosilicate glass waveguide is a good candidate for a waveguide isolator in optical fiber communication and all-optical communication. Highlights: Planar waveguides in magneto-optical glasses are formed by proton implantation. Waveguides demonstrate acceptable guiding properties. The effects of implantation on the structural and optical properties are obvious studied.
