| Abstract: | Planar optical waveguides in X-cut LiNBO3 fabricated by the proton exchange techniqueusing benzoic acid as the proton source and their annealing effects have been investigatedexperimentally,On the basis ot the mode refractive indices measured by using a prism coupler,theevolution of the refractive index profiles of the waveguides with the annealing time was accuratelydetermined by using a Fermi function,The profile parameters and curves of the waveguideswere presented. |

| Keywords: | Proton exchanged waveguide Annealing effect Mode index |
