1. An optical reflector device comprising:
a substrate;
a first reflector layer on the substrate;
a chalcogenide glass layer on the first reflector layer so that the first reflector layer is between the chalcogenide glass layer and the substrate; and
a second reflector layer on the chalcogenide glass layer so that the chalcogenide glass layer is between the first reflector layer and the second reflector layer;
wherein at least one of the first reflector layer and the second reflector layer comprises a dielectric stack, and wherein the chalcogenide glass layer has an optical index of refraction that is configured to be thermally tuned while physically between the first and second reflector layers post deposition to adjust a wavelength response of the optical reflector device.
