Claim:
1. A method comprising: selecting a design wavelength; determining a spacing parameter corresponding to the design wavelength; forming a conducting surface; forming a dielectric layer on the conducting surface corresponding to the spacing parameter; and distributing a plurality of conducting nanoparticles on the dielectric layer, wherein distributing the conducting nanoparticles includes distributing a plurality of conducting nanoparticles that each have at least one substantially planar surface, and wherein the planar surface is oriented substantially parallel to the conducting surface and supports a resonant gap-plasmon guided mode within a gap between the nanoparticle and conducting surface, and the resonant gap-plasmon guided mode is an interferometric cavity resonance corresponding to a build-up of a stationary wave in the gap.
