Abstract

2D arrays of cylindrical and rectangular gold nanopillars in square and triangular lattice were investigated for maximum field intensity enhancement above the metal dielectric interface. 3D-FDTD method was used for investigation and design of metallic photonic crystal. Photonic crystal was designed for maximum electromagnetic field intensity enhancement in infrared radiation centered at 980 nm wavelength. It was found that gold nanopillars of thickness 70nm, diameter 310nm and periodic in 620nm enhances the electromagnetic intensity by 100 times above the metallic nanopillars by exciting surface plasmon resonance. Enhancement of near-field intensity by two orders of magnitude is the promising way to increase the upconversion of infrared radiation by rare earth doped nanoparticles, such as NaYF₄:Er,Yb.
