Abstract
The processing of information is performed using a magneto-optic circuit that modifies the polarization of light using the Kerr effect. Magneto-optic circuits perform digital-to-analog conversion, comparison of values, and mathematical operations. Current carrying wires pass near a fiber-optic that carries polarized light. Each individual wire contributes a modification to the polarization of the light based on the current carried in each wire. The modified light is passed through a polarizer, and the intensity of the light may be measured with a photodiode to produce an electrical signal representing a result.
