Abstract
An infrared high-pass plasmonic filter includes a copper layer interposed between two layers of a dielectric material. An array of patterned openings extend through the copper layer and are filled with the dielectric material. Each patterned opening is in the shape of a greek cross, with the arms of adjacent patterns being collinear. A ratio of the width to the length of each arm is in the range from 0.3 to 0.6, and the distance separating the opposite ends of arms of adjacent patterns is shorter than 10 nm.
