In the present work the junction of two thermoelastically different materials stuck together has been used as a thermoelastic transducer of surface acoustic waves. A simplified theoretical analysis gives a criterion of convenience for the pair of materials to be used. The experiments carried out proved the efficiency of such a source of surface acoustic waves.

    Numerical calculations are employed to study the modulation of light by surface acoustic waves (SAWs) in photonic band gap (PBG) structures. The on/off contrast ratio in a PBG switch based on an optical cavity is determined as a function of the SAW-induced dielectric modulation. We show that...
