Planar waveguides were produced in single crystals of BaTiO 3 by thermally controlled implantation of helium or hydrogen. Their waveguide properties were investigated by dark line mode spectroscopy. The refractive index profiles were reconstructed by an inverse Wentzel-Kramers-Brillouin (WKB) proced
