Abstract


On the basis of a Maxwell-Bloch Langevin approach we study the dynamics of nanoplasmonic metamaterial lasers. We report that lasing of the bright negative-index mode is possible if the higher-Q dark mode is discriminated by gain, spatially or spectrally. The nonlinear competition during the transient phase is followed by steady-state emission where bright and dark modes can coexist. We analyze the influence of pump intensity and polarization and explore methods for mode control.
