  • Abstract
    In this paper, planar waveguides produced by He-ion implantation have been demonstrated in undoped and Yb-doped KY(WO4)2 crystals. The effective refractive indices of guided modes in surface planar waveguides were measured by dark m-line spectroscopy and the refractive index profiles were reconstructed by calculations based on the inverse WKB method. The end-faces of implanted crystals were polished and the waveguiding properties of the obtained planar structures were investigated using a laser diode at 980 nm and a CCD camera.
