Abstract
The invention comprises a solid state infrared source apparatus and method of use thereof, comprising: (1) an electrically conductive film comprising: an emission side and a back side opposite the emission side and a surface area to height ratio of at least five hundred to one; (2) a first dielectric film contacting the back side of the electrically conductive film; and (3) a reflective layer, the reflective layer embedded in the solid state source between the first dielectric film and a support layer, wherein the electrically conductive film emits infrared light upon warming with an electrical current during use, the infrared light sequentially reflecting off of the reflective layer, transmitting through the electrically conductive film, and emitting from the solid state source. Preferably the electrically conductive film comprises zinc oxide and the reflective layer is deposited into a basin in a second dielectric film.
