Paper Abstract

Recently, we proposed a new speckle-based hologram multiplexing recording technique. In this method, a multi-mode LiNbO3 single crystal fiber is employed to generate speckle patterns which are used as reference beams in hologram recording process. The speckle pattern generation can be precisely controlled by external E-field. Theoretically, this technique can generate thousands of decorrelated reference beams at given practical constraints. The system storage capacity has so far been estimated based on idealized settings. As it is well known that, besides the limitation set by the modulation mechanism capacity the storage density of a volume hologram memory system can be also restricted by many other factors. Among all factors, the crosstalk is a fundamental one that may ultimately put a tighter bound to system storage capacity. This paper is devoted to the theoretical analysis and numerical simulation of crosstalk in this proposed technique.
