Practical metamaterial lenses for plasmonic applications

ORAL

Abstract

We explored two-dimensional plasmonic metamaterial lenses using surface plasmon polariton (SPP) tomography techniques. Metamaterial lenses were defined by a periodic array of air holes patterned on a thin film polymethyl methacrylate (PMMA) deposited in a typical Au/glass nanostructure. Surface emission and Fourier-plane images of SPP beams through the plasmonic lenses were analyzed to extract the lens focal length. The experimental extracted values show very good agreement to calculated values using conventional thin-lens equation. These practical plasmonic lenses are attractive for integrated plasmonic devices and lab-on-chip applications.
