Paper Abstract

A new method of beam shaping by spatially inhomogeneous polarization is proposed and studied. Unlike the conventional techniques, the polarization state in the pupil plane of a far-field beam shaping system is modulated in a spatially variant pattern. It is shown that with carefully designed polarization manipulation, the smallest flat-top intensity focal pattern can be obtained. Theoretical analysis demonstrates the uniqueness of this new idea in terms of the size of the flat-top spot; experiments are described that successfully demonstrate the feasibility of this method to practical applications.
