1. A graphene plasmon resonator, comprising:
a planar patterned layer comprising:
a plurality of electrically conductive segments; and
a plurality of dielectric segments, each dielectric segment defined between a corresponding pair of the plurality of electrically conductive segments,
wherein the plurality of electrically conductive segments and the plurality of dielectric segments are sized and spaced to establish a resonance frequency of a graphene plasmon mode, the resonance frequency corresponding to a predetermined wavelength of electromagnetic radiation;
a graphene layer substantially parallel to the planar patterned layer and overlapping the plurality of electrically conductive segments; and
a planar dielectric layer between the planar patterned layer and the graphene layer.
