Polychromatic nanofocusing of surface plasmon polaritons
Wei Liu, Dragomir N. Neshev, Andrey E. Miroshnichenko +2
We introduce the concept of polychromatic plasmonics and suggest an broadband plasmonic lens for nanofocusing of surface plasmon polaritons. The lens employs a parabolically modula…
Influence of the backward propagating waves on the threshold in planar nematic liquid crystal films
Dmitry O. Krimer, Andrey E. Miroshnichenko, Etienne Brasselet
We analyze theoretically the influence of backward propagating waves on the primary threshold when a linearly polarized light impinges at normal incidence on a planarly aligned nem…
Complete spectral gap in coupled dielectric waveguides embedded into metal
Wei Liu, Andrey Sukhorukov, Andrey Miroshnichenko +4
We study a plasmonic coupler involving backward (TM_01) and forward (HE_11) modes of dielectric waveguides embedded into infinite metal. The simultaneously achievable contradirecti…
Optomechanics of liquid crystals for dynamical optical response of photonic structures
A. E. Miroshnichenko, E. Brasselet, D. O. Krimer +1
We show that the mechanical effect of light on the orientational ordering of the crystalline axis of a mesophase can be used to control the dynamics of the optical response of liqu…
