A True Assessment of Flat Lenses for Broadband Imaging Applications
Jacob Engelberg, Uriel Levy
A plethora of metalenses and diffractive lenses (flat lenses) have been demonstrated over the years. Recently, attempts have been made to stretch their performance envelope, partic…
Achromatic diffractive lens limits
Jacob Engelberg, Uriel Levy
Over the recent years, there have been many reports of achromatic metalenses and diffractive lenses. However, very few (if any) practical applications of such achromatic flat lense…
How good is your metalens? Experimental verification of metalens performance criterion
Jacob Engelberg, Talia Wildes, Chen Zhou +4
A metric for evaluation of overall metalens performance is presented. It is applied to determination of optimal operating spectral range of a metalens, both theoretically and exper…
Near-IR wide field-of-view Huygens metalens for outdoor imaging applications
Jacob Engelberg, Chen Zhou, Noa Mazurski +3
The ongoing effort to implement compact and cheap optical systems is the main driving force for the recent flourishing research in the field of optical metalenses. Metalenses are a…
