Paper Abstract

We discuss the compound set of two dielectric microspheres to confine light in a three dimensional region of dimensions on the order of the wavelength when the spheres are illuminated by a plane wave. This simple configuration enables the reduction of the longitudinal dimension of so called photonic jets, together with a strong focusing effect. The beam shaped in that way is suitable for applications requiring high longitudinal resolutions and/or strong peak intensities.
