Abstract

We experimentally investigated the map of the momentum of photons of propagating modes in dye-doped dielectric loaded plasmonic quasi-crystals with 12-fold symmetry. Using Fourier plane image analysis we established the relation between the pseudo-Brillouin zone and the directivity of propagating modes in plasmonic quasi-crystals with different periods at different frequencies. We demonstrated that a full isotropic bandgap can be achieved with the proposed structures.
