ABSTRACT:
A device for realizing logical operations operates extremely fast and exhibits the particular advantage that it can be converted from one logical operation to another so that a plurality of logical operations can be realized with a single component. The device comprises an operation channel which includes a light path for linearly-polarized light, an analyzer which comprises a polarization filter and an operation control which influences the plane of polarization of the polarized light and can controllably alter its rotary position. The rotary position of the plane of polarization of the light is binarily evaluated by the analyzer. The operation control is controlled by logical variables and the logical operation can be modified by one or more separate inputs. Such an embodiment exploits the Faraday effect. A similar device in another embodiment exploits the Pockels effect in which the phase of the light is changed and evaluated with respect to a reference phase.
