A key goal of metalens research is to achieve wavefront shaping of light using optical
elements with thicknesses on the order of the wavelength. Such miniaturization is expected …

The imaging of microscopic biological samples faces numerous difficulties due to their small
feature sizes and low-amplitude contrast. Metalenses have shown great promise in …

In this Letter, we experimentally report an achromatic metalens (AML) operating over a
continuous bandwidth in the visible. This is accomplished via dispersion engineering of …

Optical metalens has been attracting more and more attention in recent years. To date, it is
still difficult to simultaneously achieve wide field and broadband imaging in the visible …

Midinfrared devices based on metalenses are of great utility for numerous applications,
