Nature inspired design methodology for a wide field of view achromatic metalens.

ABSTRACT: Metalenses have become ubiquitous in academic research and have begun to make their transition to industry. However, chromatic aberration still greatly limits the applications of metalenses. Achieving a wide field-of-view (FOV) is another challenge that has been dealt with successfully by using a removed stop, but when combined with a broadband spectrum, lateral chromatic aberration severely limits performance. In this paper, we tackle this challenge and present a comprehensive design methodology for a simultaneously wide-FOV and achromatic metalens, which is inspired by the human visual system. As a design example, we present a metalens operating in the near infrared (NIR), with 10 % relative spectral bandwidth (807-893 nm), focal length of 5 mm, F/5, and FOV of ±20°. In particular, we sh
