This review discusses the composition and applications of meta-lenses, emphasizing their importance and potential applications in different fields. Furthermore, it outlines the current challenges in the field and future directions for development.
A meta-lens is an advanced flat optical device composed of artificial antennas. The amplitude, phase, and polarization of incident light can be engineered to satisfy the application requirements of meta-lenses. Meta-lenses can be designed to achieve a variety of functions, such as diffraction-limited focusing, high focusing efficiency, and aberration correlation, which are useful in various application scenarios. This review focuses on the recent progress in meta-lenses, from fundamentals to applications. The present challenges in this domain are summarized and future prospects are offered. The primary aim of this review is to provide the reader with a comprehensive understanding of meta-lenses and potential inspiration for designing high-performance meta-lenses for feasible applications.
