Fabrication of perfect plasmonic absorbers for blue and near-ultraviolet lights using double-layer wire-grid structures
Keyword(s):
Abstract This study proposes using double-layer wire-grid structures to create narrow-band, perfect plasmonic absorbers, which depend on polarization, for the short-wavelength visible and near-ultraviolet regions of the electromagnetic spectrum. A rigorous coupled-wave analysis reveals that the maximum absorption attained using Ag and Al is ~90% at 450 nm and 375 nm. Experiments using Ag yielded results similar to those predicted by simulations. These results demonstrate that narrow-band perfect plasmonic absorbers, which depend on the polarization, can be realized at 450 nm and 375 nm using Ag or Al.
