摘要：

We have analysed by means of dark and bright light spectroscopy the c-polarised mode spectra of KNbO3 planar wave,guides. These waveguides were fabricated by He+ ion implantation with ion doses from 2.5 X 10(14) to 3 X 10(15) cm(-2) and ion energies from 1 to 2.9 MeV. A quantitative model is derived to correlate the index profile of n(c) with the implantation parameters. The results are in excellent agreement with profiles observed by measuring the surface reflectivity of wedge polished samples. The test of the mode spectra after partial surface stripping by ion sputtering does not evidence irregular structures in the index profile.
