複素Hebb学習則で荷重を体積ホログラムに書き込むことによる周波数多重コヒーレント・ニューラルネットワーク・システム

We propose a coherent neural network system whose synaptic weights are embedded in volume hologram and the behavior can be controlled by lightwave carrier frequency modulation. We utilize wavelength-multiplexing technique to record synaptic weights at multiple discrete frequencies. A frequency-dependent learning of the system obeys the complex-valued Hebbian rule. The phase modulation of input and output signal beams are realized by spatial light modulators. The interference of the beams generate synaptic weights optically in a volume hologram.Experiments demonstate that the system learns various output values dependently on the carrier frequency.
