First claim
Opening claim text (preview).
That which is claimed is: 1 . An optical detector device comprising: a substrate; a reflector layer carried by said substrate; a first dielectric layer over said reflector layer; and a graphene layer over said first dielectric layer and having a perforated pattern therein. 2 . The optical detector device of claim 1 wherein the perforated pattern comprises a square array of openings. 3 . The optical detector device of claim 2 wherein each of the openings is circle-shaped. 4 . The optical detector device of claim 1 wherein the perforated pattern is symmetrical. 5 . The optical detector device of claim 1 wherein said first dielectric layer comprises a polymer material. 6 . The optical detector device of claim 1 wherein said graphene layer comprises a monolayer of graphene. 7 . The optical detector device of claim 1 further comprising: a second dielectric layer over said graphene layer; a first electrically conductive contact coupled to said second dielectric layer; and a second electrically conductive contact coupled to said graphene layer. 8 . The optical detector device of claim 1 wherein said reflector layer comprises cold material. 9 . The optical detector device of claim 1 wherein said reflector layer has a thickness greater than a threshold thickness for optical opacity. 10 . An optical detector device comprising: a substrate; a gold reflector layer carried by said substrate; a first dielectric layer over said gold reflector layer; a graphene layer over said first dielectric layer and having a perforated pattern defining a square array of openings; a second dielectric layer over said graphene layer; a first electrically conductive contact coupled to said second dielectric layer; and a second electrically conductive contact coupled to said graphene layer. 11 . The optical detector device of claim 10 wherein each of the openings is circle-shaped. 12 . The optical detector device of claim 10 wherein the perforated pattern is symmetrical. 13 . The optical detector device of claim 10 wherein said first dielectric layer comprises a polymer material. 14 . The optical detector device of claim 10 wherein said graphene layer comprises a monolayer of graphene. 15 . The optical detector device of claim 10 wherein said gold reflector layer has a thickness greater than a threshold thickness for optical opacity. 16 . A method for making an optical detector device comprising: forming a reflector layer carried by a substrate; forming a first dielectric layer over the reflector layer; and forming a graphene layer over the first dielectric layer and having a perforated pattern therein. 17 . The method of claim 16 wherein the perforated pattern comprises a square array of openings. 18 . The method of claim 17 wherein each of the openings is circle-shaped. 19 . The method of claim 16 wherein the perforated pattern is symmetrical. 20 . The method of claim 16 wherein the first dielectric layer comprises a polymer material.
