We present an experimental setup capable of quantitative examination of acoustic whistlers in tubes of varying lengths and diameters. It is simple enough to be used as an undergraduate lab or classroom demonstration. The setup can be used to show the

We have developed a simulation of a multiple quantum well optical correlator to investigate the effects of saturation on the correlation signal. We present the results of the modeling effort here.

Optical correlators have, for over three decades, been considered as attractive alternatives to digital image processing for a variety of pattern recognition tasks1. Until recently however, there has been a lack of appropriate materials with which to

We describe a class of nonlinear optical field cross-correlation processes capable of producing a high contrast subpicosecond optical gate with long broadband laser pulses. Two of the techniques, coherent anti-Stokes Raman scattering and coherently a

We have measured the diffusion coefficient of strongly interacting "colloidal liquids" near the "liquid"-"solid" phase transition using nondegenerate two-wave mixing. We self-consistently calculate the diffusion coefficient as the product of the elas

Work on deterministic instabilities and chaos over the past decade has largely focused on spatiotemporal behavior. In connection with fluids and, more recently, laser dynamics, spatial structures have played an increasingly important role. In this wo

Nondegenerate two-wave mixing (NDTWM) has been previously used to measure the relaxation time of solid-state systems. In an artificial Kerr medium, the relaxation time is the time for a particle to diffuse a portion of the index grating induced by ra

An improved design for optically addressed multiple-quantum-well spatial light modulators is reported. These integrated AlGaAs modulators are of high optical quality and are simple to fabricate. They exhibit excellent performance characteristics such

The gray-scale response of spatial light modulators based on perpendicular-field photorefractive multiple quantum wells is studied. It is shown that the gray scale exhibits both linear and saturated regimes that are accessible by variation of the app
