Infrared wavelength selective thermal emissions based on Tamm plasmon are experimentally demonstrated with ultra-sharp resonance. The excitation of Tamm plasmon polaritons (TPPs) occurs between a distributed Bragg reflector (DBR) and a metal film. Unlike conventional TPP structures having a thin metal layers on a DBR, the proposed structure have a thick metal under a DBR. The optimized number of the DBR pairs has to satisfy the impedance matching condition, which varies with the metal film. The proposed structure could achieve twice higher Q-factor for the measured emissivity comparing to typical plasmonic thermal emitters.
