Abstract


One-dimensional plasmonic photonic crystals (1D PPhCs) terminated by noble metals have been studied experimentally and analyzed theoretically. Such a PPhC supported (i) optical resonances (optical Tamm state [1, 2] and Fabry-Perot resonance) originating from periodicity of their lattices and (ii) the surface plasmons resonance on the noble metal layer. Parameters of the crystals and coupling conditions were chosen such that the optical Tamm state, the Fabry-Perot resonance and the surface plasmons resonance were excited simultaneously by light from a selected spectral range. Tuning the overlap of these resonances by a variation in coupling conditions resulted in phenomena where the optical Tamm state and the Fabry-Perot resonance were strongly modified–switched ON/OFF and interchanged by the stored energy–by slight alterations of the surface plasmons resonance.
