Imaging with flat optics: metalenses or diffractive lenses?

Sourangsu Banerji, Monjurul Meem, Berardi Sensale-Rodriguez +1

The paper compares metalenses and multi‑level diffractive lenses for imaging, showing that properly designed diffractive lenses can outperform metalenses and are easier to fabricat…
