The bandwidth of holographic recording in LiNbO<sub>3</sub> (Fe doped) in the 90° geometry is studied theoretically and experimentally. The wide holographic bandwidth of LiNbO<sub>3</sub> makes it possible to record submicrometer pixels and reconstruct them by phase conjugation in a holographic memory system. This approach reduces the system cost and increases the system storage density. We demonstrate the recording and the phase-conjugate reconstruction of various pixel sizes down to 1 μm×1 μm . The signal–noise ratio and the bit-error rate are examined.
