Abstract
An optical device comprises a first meta-lens and a second meta-lens. The first meta-lens includes a first plurality of nanostructures that define a first phase profile of the first meta-lens. The second meta-lens includes a second plurality of nanostructures that define a second phase profile of the second meta-lens. A combination of the first meta-lens having the first phase profile and the second meta-lens having the second phase profile is configured to achieve a diffraction-limited focusing and correct an aberration of light transmitted through the optical device.
