Abstract


To design and optimize active nanoplasmonic devices, accurate models of the interaction of light with organic dyes are required. Here, we present a numerical tool for time-domain modeling of high-optical-gain dyes that solves the general multiphysics problem of coupling the system of time-dependent multilevel rate equations with the classical electrodynamics of light propagation. We discuss the importance of introducing more realistic models, such as the 5-level and 6-level systems with split transitions that can be used for the analysis of pump-probe dynamics from experiment, coherent effects, as well as the experiment-fit modeling of vibrational structure in the absorption and emission spectra of a given host-embedded dye.
