Experimental demonstration of a beam shaping non-imaging metasurface

Year: 2025

Type: article

Abstract: Light emitting diodes have superior performance over most other light sources, but the need for secondary optics to shape their illumination for specific applications yield bulky lighting products. Here, we present an approach to shaping light from incoherent sources, such as light emitting diodes, using non-imaging metasurfaces. We present a theoretical framework and a numerical tool for designing the metasurface phase, and use it to construct a proof-of-principle beam shaping metasurface. We demonstrate the optical performance of the fabricated sample, and perform numerical experiments to investigate the quality of the metasurface design. Our approach bridges the fields of non-imaging optics and metaoptics, and may enable metasurface applications for shaping coherent and incoherent light.
