Abstract

We present wavelength-multiplexed holographic recording for high-density, high-speed data storage using reflection geometry with a high-sensitivity cerium-doped strontium barium niobate single-crystal structure and second-harmonic generated light from a compact and convenient wavelength-tunable laser diode. We have recorded and reconstructed wavelength-multiplexed holograms by using wavelengths 0.053-nm apart. The theoretical wavelength selectivity of the hologram with the linewidth of the light source taken into consideration agrees well with the experimental wavelength selectivity.
