High-contrast optical modulation by 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 these structures exhibit high contrast ratios even for moderate acousto-optic coupling. PACS: 42.79.Ta, ...

Capillary wave motion excited by high frequency surface acoustic waves

This paper presents a numerical and experimental study of capillary wave motion excited by high frequency surface acoustic waves SAWs . The objective of this study is to provide insight into the dynamic behavior of the fluid free surface and its dependence on the excitation amplitude. A two-dimensional numerical model that couples the motion of the piezoelectric substrate to a thin liquid layer...

Aligning Nanowires by Standing Surface Acoustic Waves

We present a standing surface acoustic wave (SSAW) based approach to achieve one-dimensional (1D) and two-dimensional (2D) alignment of nanowires (NWs). Our SSAW-based nanowire-aligning technique can be used to construct large-scale (e.g., centimeter scale) network of nanowires within 5 min. In this approach, we use interdigital transducers deposited on a piezoelectric substrate to generate dif...

Solitary surface acoustic waves.

Solitary acoustic pulses can propagate along the surface of a coated homogeneous and inhomogeneous medium. It is shown how these nonlinear surface acoustic waves evolve out of initial pulselike conditions generated by pulsed laser excitation and how they can be monitored by optical detection. The solitary pulse shapes at the surface are computed on the basis of an evolution equation with nonloc...

Thermo-optical modulation of ultrasonic surface waves for NDE.

The well-known thermo-elastic effect of laser irradiation can be exploited to produce strong localized stresses when an expanded, long pulse, low-intensity laser beam is used to irradiate the specimen. These stresses will produce a parametric modulation of the received ultrasonic signals, that is somewhat similar to the acousto-elastic effect often used in nonlinear ultrasonic studies. It is sh...
