Claim:
1. A plasmonic device comprising: a conductor layer having a top surface and a bottom surface, the bottom surface of the conductor layer disposed directly on a surface of a substrate, wherein the conductor layer comprises an input conductor segment, an output conductor segment, and a first manipulation segment separating the input conductor segment and the output conductor segment, wherein the first manipulation segment comprises a first semiconductor segment disposed only on a top surface of a first insulator segment, and the first insulator segment disposed only on a top surface of a first conductor segment; an insulator layer having a top surface and a bottom surface, an input end, and an output end, the bottom surface of the insulator layer disposed only on the top surface of the conductor layer; and a hybrid layer having a top surface and a bottom surface, the bottom surface of the hybrid layer disposed only on the top surface of the insulator layer, wherein the hybrid layer comprises an input conductor segment, an output conductor segment, and a second manipulation segment separating the input conductor segment and the output conductor segment, wherein the second manipulation segment comprises: a second conductor segment disposed only on a top surface of a second insulator segment, and the second insulator segment disposed only on a top surface of a second semiconductor segment, and wherein the hybrid layer is disposed only on the top surface of the insulator layer, wherein a first gate voltage is applied between the second conductor segment and the second semiconductor segment of the hybrid layer, and a second gate voltage is applied between the first conductor segment and the first semiconductor segment of the conductor layer such that a plurality of surface plasmon polaritons (SPP) propagates from the input end to the output end of the insulator layer when the first gate voltages and the second gate voltage are set to accumulate the semiconductor segment of the hybrid layer via an electric field, and the SPP propagation ceases when the first gate voltages and the second gate voltage are set to deplete the semiconductor segment of the hybrid layer and the second semiconductor segment of the conductor layer via the electric field.
