Claim Text:
1. A plasmonic laser comprising plasmon resonant cavities filled with an active gain medium, wherein the plasmon resonant cavities comprise: a planar substrate; and an array of metal-coated dielectric nanowires end-connected substantially orthogonally to the planar substrate and in parallel arrangement with each other so that plasmon resonant gap-cavities capable of supporting propagation of gap plasmon modes are formed between adjacent pairs of said nanowires with one end of each of said plasmon resonant gap-cavities delimited by a surface of the planar substrate and another end of each of said plasmon resonant gap-cavities open ended, and wherein the gain medium comprises a solution of an organic dye having an absorption maximum at a first wavelength and an emission maximum at a second wavelength, wherein absorption at the first wavelength produces a population inversion in the gain medium, and wherein the plasmon resonant cavities have a plasmon resonance or resonances that substantially align with the absorption and emission maxima of the dye.
