Abstract

An optical hybrid lens comprises a substrate having a first surface and a second surface opposite the first surface. A sub-wavelength grating lens is disposed on the first surface and comprises a plurality of posts. The plurality of posts is arranged on the first surface and the posts extend from the first surface. A refractive lens is arranged on the sub-wavelength grating lens at least partly enclosing the plurality of posts. Alternatively, the refractive lens is arranged on the second surface.
