Controlling plasmon-exciton coupling through band gap engineering of plasmonic crystals is demonstrated in the Kretschmann configuration. When the flat metal surface is textured with a sinusoidal grating only in one direction, using laser interference lithography, it exhibits a plasmonic band gap because of the Bragg scattering of surface plasmon polaritons on the plasmonic crystals. The contra...

We investigate electronic transport in lithographically patterned graphene ribbon structures where the lateral confinement of charge carriers creates an energy gap near the charge neutrality point. Individual graphene layers are contacted with metal electrodes and patterned into ribbons of varying widths and different crystallographic orientations. The temperature dependent conductance measurem...

We establish dispersion engineering rules that allow us to control the thermalization process and thermal state of an initial beam propagating in a multimode nonlinear photonic circuit. To this end, we have implemented kinetic equation (KE) approach systems whose Bloch relation exhibits bands gaps. When ratio between gap-width band-width is larger than critical value, KE has stationary solution...
