Rabi oscillations in spasers during the nonradiative plasmon excitation

TL;DR

This paper investigates the nonlinear dynamics of spasers, revealing that Rabi oscillations of quantum dots in nanoparticle fields cause complex oscillatory behavior during nonradiative plasmon excitation.

Contribution

It demonstrates that Rabi oscillations are responsible for the nonlinear dynamics in spasers and shows their dependence on initial conditions.

Rabi oscillations cause nonlinear dynamics in spasers

Oscillations depend on initial conditions

Nonradiative plasmon excitation involves anharmonic oscillations

Abstract

In the approach to the stationary regime, a spaser exhibits complicated and highly nonlinear dynamics with anharmonic oscillations.1 We demonstrate that these oscillations are due to Rabi oscillations of the quantum dot in the field of the nanoparticle. We show that the oscillations may or may not arise dependent on the initial conditions.
