Abstract

In this paper, we report on the fabrication of planar waveguides in z-cut Nd:SGG crystals, using 500 keV He ion implantation with fluences of 3 × 10 16 ions / cm 2 at 77 K 1 × 10 16 ions / cm 2 at room temperature, annealed at 260 ° C for 30 min . The guiding modes of the planar waveguides were measured by the prism-coupling method at 633 nm . The near-field intensity distribution and propagation loss of the light in the waveguides were measured by the end-fire coupling method. The absorption spectra were also measured. The refractive index profile was reconstructed using the intensity calculation method, and the light propagation mode was simulated with the finite-difference beam propagation method. The calculated results were in good agreement with the measured waveguide modes, indicating the feasibility of these designable devices.
