Abstract

Volume holographic data storage is a promising alternative to current surface storage technologies, since it can provide simultaneously large digital storage capacity, fast data transfer rates, and short access times [1]. This is achieved by storing multiple holographic data pages in a common recording volume, while retaining the ability to retrieve any individual page. Multiplexing of data pages can be performed either at one wavelength, using angular or phase- encoded multiplexing, or at different wavelengths, using wavelength multiplexing. This investigation focuses on phase-encoded multiplexing, which for example allows direct binary arithmetic operations on recorded pages and enables data encryption [2].
