Patent abstract

A thermal emitter device includes a cavity structure that comprises an active medium for allowing thermal emissions to occur. A photonic crystal structure is positioned on one side of the cavity structure. The photonic crystal structure comprises alternating layers of high index and low index materials and acts as a first mirror for the cavity structure. A highly reflective mirror structure is positioned on another side of the cavity structure and acting as both the high-temperature source of radiation and a second mirror for the cavity structure.
