We present an overview of our research effort on volume holographic digital data storage.
Innovations, developments, and new insights gained in the design and operation of working …

One thousand volume holographic data pages, each containing 1× 10^ 6pixels, are stored
in a common volume of LiNbO_3: Fe by use of the 90° geometry. An effective transverse …

This correspondence introduces a framework to design and analyze low-density parity-
check (LDPC) codes over nonuniform channels. We study LDPC codes for channels with …

The low-pass nature of the optical systems (both coherent and incoherent) used for volume
optical storage results in the presence of intersymbol interference (ISI) at the output of these …

Abstract Unequal Error Control (UEC) codes provide means for handling errors where the
codeword digits may be exposed to different error rates, like in two-dimensional optical …

We report a simple and stable phase detection method for holographic data storage
systems. Our method needs only one image acquisition, and no additional light waves or …

We investigate the application of low-density parity-check (LDPC) codes in volume
holographic memory (VHM) systems. We show that a carefully designed irregular LDPC …

Volume optical storage systems suffer from numerous sources of noise and interference, the
effects of which can seriously degrade retrieved data fidelity and produce unacceptable bit …

Holographic data storage (HDS) is an emerging technology that promises to revolutionize
digital data storage and access. Unlike traditional storage media such as hard drives and …
