Broadband, High-Efficiency, Large-Aperture Metalenses in the Visible

Abstract

We developed a design for a high efficiency, broadband metalens –Used a heuristic approach, based on mature diffractive optic design methods –> 90% transmission efficiency in each of the red, green and blue color bands –Maintains performance out to > 10 10°AOI •Metalens can be used to correct aberrations in multi element optical systems –Corrective doublets –Multi Acknowledgement of Support and Disclaimer This material is based upon work supported by the Defense Advanced Research Projects Agency (DARPA) under Contract No. 140D0420C0065.
