摘要
In this disclosure, an optical component which comprises an array of metalenses is provided. Each metalens comprises a plurality of nanostructures and a dielectric layer and the nanostructures are disposed on the dielectric layer, and the nanostructures comprises an array of first phase compensation structures, and an array of second phase compensation structures. The array of the first phase compensation structures are disposed to surround the array of the second phase compensation structures so as to define a single metalens. The first and second phase compensation structures are complementary to each other and substantially satisfy the Babinet's principle.
