Paper Abstract

Recently, 3D silver nanolenses with concentric slits with an on-axis stop and with concentric corrugations on both surfaces and no hole on the optical axis were proposed. The nanolenses illuminated with a radially polarized visible range Laguerre-Gauss beam focus light into subwavelength spots and act as high numerical aperture refractive optical systems. Focal lengths range from one to a few wavelengths. Due to constructive interference of far-field radiation of SPPs generated on the back side the lens focuses without contribution of the evanescent field. In this technical note we investigate transmission and focusing properties of lenses of both kinds made of different metals: silver, gold, copper, and aluminum.
