Emission enhancement in hybrid Tamm plasmon/photonic quasicrystal structure

We have theoretically demonstrated that Tamm plasmon structure with photonic quasicrystal instead of usual distributed Bragg reflector can support hybrid Tamm plasmon-like optical eigenstates.

Also, evaluation of the modal Purcell factor for hybrid structure demonstrates significant enhancing of spontaneous decay rate for emitter coupled with Tamm plasmon-like states. The results can be used in fabrication of high-efficient organic-based light emission systems.
