Inverted plasmonic lens design for nanometrology applications

Abstract: Planar plasmonic lenses have attracted a great deal of interest over the last few years for their super-resolution focusing capabilites. These highly compact structures with dimensions of only a few micrometres allow for the focusing of light to sub-wavelength-sized spots with focal lengths reaching into the far-field. This offers opportunities for new methods in nanometrology; for example, applications in microscopic Mueller matrix ellipsometry setups. However, the conventional plasmonic lens is challenging t… Show more

“…2 E-field intensity on xz-plane along y axis for h hollow = 50 nm, 100 nm and 140 nm at corresponding λ d . For increasing h hollow , λ d redshifted due to larger penetration depth of surface plasmon polariton (SPP) at longer wavelengths [42]. It was experimentally proven that E-field intensity could increase at top metal edge with the decrease of nano-aperture height, which is denoted by h hollow in our design [43].…”
