Abstract
A meta-lens having a phase profile includes a substrate and a plurality of nanostructures disposed on the substrate. The nanostructures together define the phase profile of the meta-lens. The phase profile achieves an off-axis focus. Each nanostructure is designed according to at least one design parameter of the nanostructure that imparts a phase shift of light passing through the nanostructure.
