Abstract
Light structured in phase and polarization has proven extraordinary benefit for optical tweezing. However, the customization of focal, non-paraxial light landscapes still poses a challenge. We tailor novel focal landscapes including its intensity as well as three-dimensional polarization structure by complex vector beams, even combined with phase vortices. By focusing vector fields, whose polarization is oriented in flower- or web-shape, we fabricate intensity structures resembling bright flowers or dark stars. These structures are formed by transverse Ex,y as well as longitudinal Ez electric field components. We tune the z-polarization components as well as threedimensional focal volume E (x, y, z) = [Ex, Ey, Ez]T on demand, optimizing its structure for optical trapping applications. Beyond, we prove their benefit for advanced optical trapping schemes by tweezing and orienting zeolite-L nano-containers.
