  • Abstract
    A waveguide supporting a single propagating mode has been fabricated by ion beam modification of X-cut crystal quartz. The gas ion implantation reduced the index of a subsurface layer, and guiding occurred in the surface region. The acoustic properties of the quartz are little affected. Bragg diffraction of guided light by surface acoustic waves was observed with efficiencies of approximately 0.25% per milliwatt acoustic power.
