Paper Abstract

By reading data in an angular multiplexed holographic storage system at a wavelength other than the wavelength used for writing, the problem of unwanted erasure can be prevented. By compensating data prior to recording, the mismatch resulting from the difference in reading and writing wavelengths may be minimized. Such a compensation technique was experimentally investigated by recording differentially encoded data within an Fe doped sample of LiNbO3 at a wavelength of 514 nm and recalling data using 488 nm. Our system demonstrated that the recording of compensated data allowed accurate readout with a raw bit error rate of .08%.
