Research Interests:

Optical data storage technology has dramatically increased the volume and speed that information can be manipulated. These technologies have been dominated by magnetic tape, magneto-optical and compact disc data storage devices. A relatively new technique for dramatically increasing data storage capacity is to store data holographically in photorefractive materials.

The objectives of our research are to: (1) understand the microscopic physical processes that determine the photorefractive properties of single crystal oxides, organic polymers, and semiconducting materials and (2) develop new methods and techniques for holographic data storage. Our laboratory is equipped for precise measurements of photorefractive materials using cw and pulsed laser spectroscopy.
