Paper Abstract

We show how photorefractive two wave mixing allows a nonlinear input-output response providing compational abilities of decision. Particularly, we investigate the realization of a photo-refractive "optical neuron". Signal amplification with saturation is obtained and could compensate for losses due to holograhic connections. Moreover, the treatment of bipolar signals is allowed by preserving the phase of the wave in a coherent situation. Experimental evidence, using a crystal of BaTiO3 is presented.
