Abstract

One of the unique and perhaps the most attractive features of an optical memory is its ability to store and retrieve information in a bit-parallel format.^1-3 Recently, we have proposed a new scheme for parallel data storage in TDOM.^4,5 This scheme was proven to be practical and can be implemented with existing technologies. In a proof-of-principle experiment, four wavelength-multiplexed single-page volume spectral holograms, generated with black-and-white transparencies, were successfully stored in a single spatial location at a speed of approximately 23 μs/frame. The experimental results project system's input/output bandwidth to exceed 40 Gbps, two orders of magnitude faster than a semiconductor cache memory.
