摘要:">We report on the planar waveguide fabrication in SrTiO3crystal by using carbon ion irradiation at energy of 15 MeV. The reconstructed refractive index profile of the waveguide shows the "barrier"-like distribution. The planar waveguide supports guidance along both of the TE and TM polarizations. The near-field mode distribution of the waveguide shows reasonable agreement with the simulated modal profile. After thermal annealing treatment at 260 C in air, the propagation loss of waveguide is reduced to as low as 0.8 dB/cm. © 2013 Elsevier B.V. All rights reserved.
