1. A method of making an optical device comprising:
- forming a plurality of holes with varying radii milled vertically into a film, wherein said holes form a pattern, wherein a radius of each hole determines an effective refractive index for said hole, said effective refractive index modifying a phase and an intensity of an incoming electromagnetic radiation as the radiation propagates through said hole, wherein the device is configured to be operating equally for each linearly polarized radiation simultaneously, wherein the each linearly polarized radiation is normally incident on the device.

Abstract
A method of making an optical device including forming a plurality of holes with varying radii milled vertically into a film, wherein said holes form a pattern. The radius of each hole determines an effective refractive index for said hole. The effective refractive index modifies a phase and an intensity of an incoming electromagnetic radiation as the radiation propagates through said hole. The device is configured to be operating equally for each linearly polarized radiation simultaneously, wherein the each linearly polarized radiation is normally incident on the device.
