摘要：
KTiOPO4 was implanted by 2.0 MeV and 2.8 MeV He ions with the same dose of 1.5 x 10(16) ions cm(-2) to form double barrier waveguides. The dark modes were measured by prism coupling. We have used the method of Pluck et al. to fit the refractive index profile of double barrier waveguides in KTiOPO4. The close agreement between the measured and calculated mode indices indicates that the refractive index profile obtained for double barrier waveguides in KTiOPO4 seems to be reasonable.
