Abstract

Surface plasmons have been launched from free space optical beams (at an excitation wavelength of 700 nm) and focused in the plane using concentric curved gratings (or plasmonic lenses) etched into 30 nm-thick gold films. The performance of these devices was studied with numerical simulation and verified by near-field scanning optical microscopy experiments. These plasmonic lenses have been demonstrated to focus the launched surface plasmons effectively to a high intensity focal spot.
