Paper Abstract

We here presents the first unified theory of the response of plasmonic nanoshells assisted by optical gain media. Our approach combines rigorous Mie scattering equations for the plasmonic structure and the density matrix formalism, which is well known in laser physics, allowing a correct description of different relaxation and energy exchange channels in the system. We derive a fundamental equation for calculation of SPASER frequency which we claim to be valid for any type of SPASER physical geometry. We demonstrate that ONLY radiative losses are responsible for the spasing and loss compensation process in the laser resonator.
