A refractory wavelength selective thermal emitter is experimentally realized by the excitation of Tamm plasmon polaritons (TPPs) between a titanium nitride (TiN) thin film and a distributed Bragg reflector (DBR). The absorptance reaches nearly unity at approximate to 3.73 mu m with the bandwidth of 0.36 mu m in the experiment. High temperature stabilities are confirmed up to 500 and 1000 degrees C in ambient and in vacuum, respectively. When the TiN TPP structure is compared to the TiN-insulator-TiN (TiN-metal-insulator-metal (MIM)) structure, the former shows higher Q-factor, which indicates the advantage of choosing the TiN TTP structure against the MIM structure. The proposed refractory TiN TPP structure is lithography-free and scalable, which paves a way for large scale thermal emitters in practical usage.

Selective thermal emissions from the excitation of Tamm plasmon polaritons (TPPs) are demonstrated. A TPP structure is composed of a distributed Bragg reflector (DBR) and a thin metal film on top. The tunability of the thermal emission was experimentally achieved only by changing the DBR\'s photonic bandgap. Low cost and large area selective thermal emitters can be realized by TPP-based structures. (C) 2016 Optical Society of America
