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…
Generating hot carriers in plasmonic nanoparticles: when quantization does and does not matter?
Jacob B Khurgin, Uriel Levy
Plasmon-assisted hot carrier processes in metal nanoparticles can be described either classically or using the full strength of quantum mechanics. We reconfirm that from the practi…
Enhanced spin state readout of Nitrogen-Vacancy centers in diamond using IR fluorescence
Idan Meirzada, Sigal A. Wolf, Alex Naiman +2
Nitrogen-Vacancy (NV) centers in diamond have been used in recent years for a wide range of applications, from nano-scale NMR to quantum computation. These applications depend stro…
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…
Efficient optical pumping of alkaline atoms for evanescent fields at dielectric-vapor interfaces
Eliran Talker, Pankaj Arora, Yefim Barash +2
We experimentally demonstrate hyperfine optical pumping of rubidium atoms probed by an evanescent electromagnetic field at a dielectric-vapor interface. This light-atom interaction…
