摘要：

Planar optical waveguides have been formed in Z-cut KTP materials by He+ ion implantation, Guided modes's spectra and refractive index profiles n(x), n(xy), n(y) and n(z) are determined from dark m-lines spectroscopy and by using an IWKB method. The coupling efficiency and light confinement are better with TM (n(z)) modes than TE ones. This could be explained by the cristallographic axes orientation with respect to the propagation direction. The anisotropy investigation of the waveguide will end this work.
