A polychromatic neural net using a (Ce:Fe)-doped LiNbO3 photorefractive crystal is presented. This neural net is a two-level high-content addressable memory. The first level is a polychromatic Hamming net for color image classification, and the second level is a mapping net, based on a photorefractive crystal associative memory. The major advantage of this neural net is the large storage capacity and it requires a fewer interconnection links. Experimental demonstrations are provided, in which is shown that the proposed neural net is consistent with the theoretical model.
