We report on the optical waveguides, in both planar and ridge configurations, fabricated in LiTaO 3 crystal by using carbon (C 5+ ) ions irradiation at energy of 15MeV. The planar waveguide was produced by direct irradiation of swift C 5+ ions, whilst the ridge waveguides were manufactured by using femtosecond laser ablation of the planar layer. The reconstructed refractive...
We report on the planar waveguide fabrication in SrTiO 3 crystal by using carbon ion irradiation at energy of 15MeV. 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...
