| Abstract: | In this letter, we estimate the refractive index distribution in a photo-induced waveguide. The photo-induced waveguide was fabricated by scanning a focused laser beam through a lithium niobate crystal. We made use of a parametric model of refractive index distribution of the photo-induced waveguide. The results of numerical simulation on the near-field patterns of curved waveguides are compared with experimental results. |
