Abstract

Plasmonic groove structures, which are widely known for its absorbent properties of light, are numerically investigated. Genetic algorithms have been successfully used to aid in the design of two-dimensional high efficiency wide-angle plasmonic groove absorbers for visible wavelengths. The novel periodic groove structure exhibits absorption above 90% for ultra-broadband wavelengths ranging from 300 to 700nm. The resonant modes induce localized zero wavevector plasmon polaritons in the metallic material which favors absorption and may also enhance non-linear optical processes.
