Superoscillating response of a nonlinear system on a harmonic signal
D. G. Baranov, A. P. Vinogradov, A. A. Lisyansky
We demonstrate that a superoscillating in time signal may be obtained as a nonlinear response on a harmonic low-frequency input. Using the realization of a superoscillating functio…
All-dielectric nanolaser
D. G. Baranov, A. P. Vinogradov, A. A. Lisyansky
We demonstrate theoretically that a subwavelength spherical dielectric nanoparticle coated with a gain shell forms a nanolaser. Lasing modes of such a nanolaser are associated with…
Magneto-optical spaser
D. G. Baranov, A. P. Vinogradov, A. A. Lisyansky +2
We present an electrodynamical model of a novel quantum plasmonic device - magneto-optical spaser. It is shown that a spherical gain nanoparticle coated with a metallic magneto-opt…
Loss compensation by spasers in metamaterials
E. S. Andrianov, D. G. Baranov, A. A. Pukhov +3
We show that exact loss compensation can be achieved in active metamaterials containing spasers pumped over a wide range of pumping values both below and above the spasing threshol…
Exactly solvable toy model for a SPASER
D. G. Baranov, E. S. Andrianov, A. P. Vinogradov +1
We propose an exactly solvable quasi-classical model of a spaser. The gain medium is described in terms of the nonlinear permittivity with negative losses. The model demonstrates t…
