Abstract

We report on different steps in exploring the physical basis of microholographic data storage. Using highly focused laser beams, localized volume storage has been demonstrated by creating micrometer-sized holographic gratings. The present work concerns a novel approach to 3D optical storage that offers a compromise by implementing holographic volume recording within the bit-oriented storage scheme of CD/DVD technology. Multilayer storage has been demonstrated in thick samples of ULSH Aprilis photopolymer by recording up to three layers of microgratings through the depth of the photopolymer sample.
