We report on the fabrication and characterization of low-loss planar and stripe waveguides in a Nd{sup 3+}-doped glass by 6 MeV oxygen-ion implantation at a dose of 1x10{sup 15} ions/cm{sup 2}. The dark mode spectroscopy of the planar waveguide was measured using a prism coupling arrangement. The refractive index profile of the planar waveguide was reconstructed from a code based on the reflectivity calculation method. The results indicate that a refractive index enhanced region as well as an optical barrier have been created after the ion beam processing. The near-field mode profiles of the stripe waveguide were obtained by an end-fire coupling arrangement, by which three quasitransverse electric modes were observed. After annealing, the propagation losses of the planar and stripe waveguides were reduced to be {approx}0.5 and {approx}1.8 dB/cm, respectively.
