Patent ID: 8361545

Claim:
A method of manufacturing a photonic crystal with a photonic bandgap, the method comprising: forming a periodic three-dimensional structure comprising a material having a first refractive index and a plurality of gaps; and conformally depositing exposed surfaces of the periodic three-dimensional structure with a material having a second refractive index greater than the first refractive index; and wherein the material having the first refractive index comprises at least one of polyurethane, Si, SiO 2 , and Al 2 O 3 ; wherein the material having second refractive index is TiO 2 and wherein disposition of the TiO 2 upon the periodic three-dimensional structure is performed using an atomic layer deposition (ADL); and wherein disposition comprises supplying a Ti precursor for the material having the second refractive index into a reaction chamber receiving the periodic three-dimensional structure at a temperature ranging from approximately 50° C. to approximately 150° C., to coat the periodic three-dimensional structure with the Ti precursor; supplying inert gas into the reaction chamber to purge the reaction chamber; supplying an oxygen precursor into the reaction chamber to form TiO 2 on the periodic three dimensional structure through chemical reaction of the Ti precursor and the oxygen precursor; and supplying inert gas into the reaction chamber to purge the reaction chamber.
