From: Enhancement of spontaneous emission in Tamm plasmon structures

(a) Dependence of the calculated modal Purcell factor on frequency and angle of emission; (b) Emission spectrum of quantum dots; (c) Dependence of the product of the calculated modal Purcell factor and the emission spectra of quantum dots on frequency and angle of emission; (d) Experimentally measured photoemission spectra. Arrows mark the modes (TP –Tamm plasmon, PBG – photonic band gap, 1st edge – 1st edge state, 2nd edge – second edge state).
