Paper Abstract

Acousto-optic interactions are well known and widely used since long. The main applications for bulk optic devices are Bragg-cells for beam deflection and frequency shifting. Acousto-optic interactions using integrated otpical (I0) waveguides and surface acoustic waves (SAW) are very promising because of expected high efficiency. After some fundamentals we concentrate on I0 single-mode strip-waveguides which can be influenced by SAW. Three different types of structures will be discussed in detail: the surface-acoustic wave driven interferometer (SAWDIF), the surface-acoustic wave driven directional coupler (SAWDIC), both for modulation and switching, and the I0 Bragg-cell, which combines a waveguide-switch with an optical frequency shifter. Experimental results as well as applications for these structures will be presented.
