All-optical bipolar neural network with polarization-modulating neurons
Isaac Shariv, O. Gila, Asher A. Friesem · Optics Letters · 1991
A general all-optical implementation scheme for bipolar neural networks is presented. Bipolar operation is realized by exploiting two orthogonal light polarizations. A three-layer feed-forward bipolar network is demonstrated experimentally by using a liquid-crystal light valve for implementing an array of polarization modulating neurons.
