Holographic read-write memory and capacity enhancement by 3-D storage

Abstract

The capacity and limitations of fast random-access holographic memory are discussed. Capacities such 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sup> bits can be envisioned by superposition of holograms in a thick erasable storage material. The organization of the read-write holographic memory provides the possibility of varying the reference beam angle at any given point of the memory plane.
