We report the first fabrication and characterization of optical planar waveguides in Bi12TiO20 crystals by ion implantation For comparison we selected O2+ and He+ as our implanted ions The loss value of the oxygen-implanted planar waveguide is reduced to 1 24 dB/cm after annealing at 260 degrees C for 30 min The guided mode profiles are successfully modeled through numerical simulations (C) 2010 Elsevier B V All rights reserved
