Abstract

Materials and fabrication options are discussed for the implementation of three dimensional graded index of refraction diffractive metamaterial gratings and holograms. Materials choices for infrared implementation, dielectric deposition options, planarization approaches, and nanopatterning are discussed for implemented 3D GRIN metamaterial gratings and holograms operating at lambda = 10.6 um.
