In the approach to the stationary regime, a surface plasmon amplification by stimulated emission of radiation exhibits complicated and highly nonlinear dynamics with anharmonic oscillations [M. I.â€¦ (More)

We find the conditions upon the amplitude and frequency of an external electromagnetic field at which the dipole moment of a Bergman-Stockman spaser oscillates in antiphase with the field. For theseâ€¦ (More)

We show that due to near-field interaction of plasmonic particles via gain particles, a two-dimensional array of incoherently pumped spasers can be self-synchronized so that the dipole moments of allâ€¦ (More)

At the plasmon resonance, high Joule losses in a metal nanoparticle of a spaser result in its low Q-factor. Due to the latter, to achieve the spasing regime, in which the number of coherent plasmonsâ€¦ (More)

We propose an exactly solvable electrodynamical model for surface plasmon amplification by stimulated emission of radiation (spaser). The gain medium is described in terms of the nonlinearâ€¦ (More)

In contrast to Hermitian systems, the modes of non-Hermitian systems are generally nonorthogonal. As a result, the power of the system signal depends not only on the mode amplitudes but also on theâ€¦ (More)

452 1. INTRODUCTION In connection with the rapid progress of plasmonn ics in recent years [1â€“5], much interest has been attracted to the problem of the influence of interaction between twoolevelâ€¦ (More)

We show that in plasmonic systems, exact loss compensation can be achieved with the help of spasers pumped over a wide range of pumping values both below and above the spasing threshold. Weâ€¦ (More)

We suggest a mechanism by which a superradiant burst emerges from a subwavelength array of nonlinear classical emitters that are not initially synchronized. The emitters interact via the field ofâ€¦ (More)
