title: Cross-talk noise in a wavelength-multiplexed reflection-type photorefractive fiber hologram.
abstract: We have analyzed the cross-talk noise as affected by the wavelength spread that is due to the spectral width of the light source in a wavelength-multiplexed reflection-type photorefractive fiber hologram. The spectral bandwidth of each multiplexed channel limited by the cross-talk noise is discussed. The signal-to-noise (cross-talk) ratio is analyzed, whereby we have shown that this ratio is sensitive to the separation between adjacent multiplexed channels and to the spectral width of the light source. The cross-talk-limited storage capacity for practical photorefractive fibers is evaluated.
