A KTiOPO4 crystal waveguide was fabricated under the conditions of different implanted energies of He+ ions and a total dose of 2.5×1016 ions/cm2 at the temperature of nitrogen. The effective refractive index of the guided modes was measured with M line spectra after the He:KTP was annealed. The refractive index profiles of the He:KTP waveguide were calculated and proved to be in agreement with the damage profile and the range profile.
