US 2012/0235067 A1 · TUNABLE INFRARED EMITTER

Abstract

Provided are methods of tuning the emission wavelength from a tunable infrared plasmonic emitting structure, which structure comprises: (a) a perforated or patterned first conductive layer having a plurality of relief features provided in a periodic spatial configuration, wherein the relief features are separated from each other by adjacent recessed features, wherein the distance between features is between 1-15 μm; (b) a dielectric layer underlying the first conductive layer; (c) a second conductive layer underlying the dielectric film; and (d) a substrate underlying the second conductive layer; wherein the emission wavelength is tuned by applying a force in a biaxial direction parallel to the substrate, changing the distance between relief features, or changing the resistivity and dielectric constant of the dielectric layer.
