Abstract

Coherent time-domain optical memory (CTDOM) has been showing promising potentials for high-speed data storage.^1-3 Fast recording and readout of sequential digital optical data in a CTDOM at 40 Mbit/s have been demonstrated,¹ and an I/O bandwidth of several gigabits persecond is predicted for sequential recording. Recently, we have proposed a practical scheme for parallel data storage in CTDOM. 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 rate of approximately 43 kf/s.
