Cross-Talk In Wavelength-Multiplexed Holographic Memories

The cross talk between wavelength-multiplexed holograms is analyzed- The signal-to-noise ratio (SNR) is calculated for a recording schedule that places the center of each image at the null (in wavelength space) of the adjacent hologram. An asymptotic closed-form expression for the minimum SNR is derived in a general reflection geometry. The reflection geometry with counterpropagating signal and reference beams is shown to have the best SNR.
