Claim Text:
1. A method for high frequency signal transfer, comprising: providing a plasmonic signal transfer link including a first plasmonic coupler, a second plasmonic coupler spaced apart from the first plasmonic coupler to form a gap, an insulator layer formed over end portions of the first and second plasmonic couplers and in and over the gap, and a plasmonic conductive layer formed over the gap on the insulator layer to excite plasmons to provide signal transmission between the first and second plasmonic couplers; signaling between a first component coupled to the first plasmonic coupler and a second component coupled to the second plasmonic coupler; and modulating the signal transmission in the signal transfer link with a gate field provided by at least two gate structures present over the plasmonic conductive layer, wherein a gate area of a first one of the at least two gate structures is different from a gate area of at least a second one of the at least two gate structures, wherein a difference in the gate areas in said at least two gate structures produces a multi-level phase modulation.
