Detailed Technology Description

Researchers at the University of California, Santa Barbara have developed a novel material applicable to holographic data storage. This technology features low fabrication costs and largely scalable production due to simple manufacturing technique, small size, and a simple design that circumvents the need for a co-sensitizer or binder/polymeric matrix. It is easily processed into different shapes and forms, has no writing-induced shrinkage and a long shelf life. Moreover, this new class of material exhibits large storage capacity, short recording times due to a high photosensitivity, a high diffraction efficiency of about 60%, and a high dynamic range.

Background

Conventional data storage techniques store information on a two dimensional surface, a technique that is reaching its physical limits. There is a need for inexpensive, high performance material designed for holographic data storage that exhibits high information capacity, more data density, and faster readout rates. Holographic data storage is a promising alternative solution for continuing demands on bigger and faster data storage.
