摘要
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 x 10(16) ions/cm(2) at 77 K 1 x 10(16) ions/cm(2) at room temperature, annealed at 260 degrees 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. (C) 2010 Optical Society of America
