Photonic and plasmon-coupled emissions present new opportunities for control on light emission from fluorophores, have many applications in the physical biological sciences. The mechanism of influencing factors coupling between fluorescent molecules plasmon and/or photonic modes are active areas research. In this paper, we describe a hybrid photonic-plasmonic structure that simultaneously contains two modes: surface plasmons (SPs) Tamm (TPs), both which can modulate fluorescence emission. Experimental results show SP-coupled (SPCE) TP-coupled (TPCE) be observed with structure. Due to different resonant angles TP SP modes, TPCE SPCE beamed directions separated easily. Back focal plane images relative intensities changed if probes at locations inside structure, reveals probe location-dependent strengths SPs TPs. ascribed electric field distribution Here, an understanding these mode probes, is vital design suitable sensing diagnostics.
