Abstract :
We report on the fabrication and characterization of optical channel waveguide in x-cut KTiOAsO4 crystal produced by photographic masking and following direct O ion implantation at energy of 3.0 MeV and fluence of 5 × 1013 ions/cm2. Positive changes of both and refractive indices (corresponding TM and TE polarized light respectively) in the waveguide region are responsible for light waveguiding. After annealing treatment, the propagation losses of the waveguide could be reduced to 1.2 dB/cm, exhibiting acceptable guiding properties.
