An experiment using phase‐locked acousto‐optic devices is described in which accurately detuned plane‐wave writing beams produce a stable, continuously moving intensity grating for the measurement of the temporal response of photorefractive gra

We demonstrate the first weighted-coupling Y-branch switch in semiconductors. The active waveguide core contains an InGaAs/InGaAlAs chopped quantum well electron transfer structure which provides large voltage-controlled refractive index changes near

We discuss the design of a complete, compact holographic storage demonstrator based on a combination of spatial and angular multiplexing and using acousto-optic deflectors for rapid nonmechanical access. We also describe the implementation of this de

We study two kinds of quantum interference effects in transport-the Aharonov-Bohm effect and the weak-localization effect-in quasi-one-dimensional wires and rings to address issues concerning the phase-coherence length, spin-orbit scattering, and the

Thin films of pure C60 and C70 have been studied by time-resolved degenerate four-wave mixing using femtosecond optical pulses with a wavelength of 633 nm. Large optical nonlinearities were measured for both materials, with χ(3) values ≈ 10−10 e

A novel system that is capable of switching/routing two-dimensional images in arbitrary configurations is described. The switching network can be reconfigured in a few microseconds with high light efficiency.
