Abstract

We proposed and experimentally demonstrated a new method to engineer ultra-high efficiency and linear polarization achromatic meta-lens from visible to telecommunication wavelength: 660 nm to 1200 nm with 90 % efficiency. Our proposed method is a promising approach for broadband structured interfaces. This new design surpasses the current state of the art of metalens which is mainly focus on circular polarization with limited bandwidth and efficiency.
