Stockman, Mark

A processor includes a transistor pair of a first transistor and a second transistor. The first transistor of the transistor pair is coupled to a Spaser and configured to output a drive current to the Spaser to pump the Spaser. Responsive to the drive current, the Spaser outputs surface plasmon polaritons (SPPs) which are fed to a plasmonic interconnect wire. The plasmonic interconnect wire propagates the SPPs. Further, the SPPs propagated on the plasmonic interconnect wire are detected by a phototransistor. Responsive to detecting the SPPs, the phototransistor generates an output current that is fed to a gate terminal of the second transistor to charge the second transistor.
