Abstract
In one aspect, nanoplasmonic devices are described herein. In some embodiments, a nanoplasmonic device comprises a radiation transmissive substrate, a metal layer positioned on the substrate and at least one aperture extending through the metal layer to the radiation transmissive substrate, wherein width of the aperture decreases with increasing depth of the aperture.
