Paper 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.
