Light storage via stimulated brillouin scattering in an optical fiber


Journal Article

A simple method for storing optical pulses in a room-temperature optical fiber was demonstrated. The storage of optical data pulses is achieved by coherently transferring their information content to a slow-moving acoustic excitation in the fiber through their interaction with an additional optical 'write' pulse. The acoustic excitation is later converted back to the optical domain by interaction with a 'read' pulse. The write and read pulses should be much shorter than the data pulses and their area must equal π/2, to obtain high efficiency of the storage and retrieval processes. The method uses off-the-shelf components and operates at a wavelength of about 1.55 μm. Results for storage and retrieval of a sequence of multiple 2-ns data pulses demonstrate that the retrieved light replicates the input data stream with reasonable fidelity.
