Non-imaging metasurfaces for beam shaping

Abstract
We demonstrate a new versatile platform for designing non-imaging metaoptics to use with incoherent sources. We provide a phase-design method for one-dimensional beam shaping, which allows us to compute a phase profile that efficiently redistributes a collimated beam with an arbitrary intensity profile to a desired output intensity. We verify the behavior of different metasurface designs using the opensource beam propagator diffractsim as well as full-field COMSOL simulations and find the results to be in good agreement with our expectations. We believe our work successfully bridges the fields of non-imaging optics and metaoptics and constitutes a new fast and versatile tool for metasurface design.
