Shift multiplexing for holographic storage system using fiber bundle referencing

We propose a shift multiplexing method for volume holographic storage using fiber bundle referencing. The reference beam is guided by a fiber bundle and multiplexing can be implemented by shifting the recording medium for a small distance. No sidelobe or period has been found and the signal-to-noise ratio is high. Multiple images are stored in a crystal with a spatial separation of 3 μm between successive holograms.
