hybrid mode of optical states in opal-like plasmonic-photonic crystals

We present an investigation to ascertain the role of the hybrid tamm-surface plasmonic-photonic mode of optical states in light transmission of opal-like metal-dielectric photonic crystals. the mode of optical states exhibits interesting features in the control of light. transmission spectra of one-dimensional plasmonic-photonic crystal have a maximum inside photonic bandgap due to excitation of tamm plasmon in both polarizations. three-dimensional opal-like plasmonic-photonic crystals have not transmission peak in the bandgap due to unconventional tamm state. modeling different versions of plasmonic-photonic crystal, we define the conditions of existence of a polarization-sensitive photonic bandgap transmission peak in the opal-like plasmonic-photonic crystal. additionally, we also study the condition of efficient excitation of the hybrid plasmonic-photonic mode in such structures.
