Interaction and Coherence of a Plasmon–Exciton Polariton Condensate

Abstract: Polaritons are quasiparticles arising from the strong coupling of electromagnetic waves in cavities and dipolar oscillations in a material medium. In this framework, localized surface plasmon in metallic nanoparticles defining optical nanocavities have attracted increasing interests in the last decade. This interest results from their subdiffraction mode volume, which offers access to extremely high photonic densities by exploiting strong scattering cross-sections. However, high absorption losses in metals hav… Show more

“…Strong field enhancement at the regions far from the nanoparticles is one of the most prominent characteristics of SLRs and can be used to improve and coherently control light absorption [20,21], enhance emission [22][23][24][25][26][27][28][29], increase nonlinearities [30,31], and enhance the spatial coherence [32,33]. Another characteristic is their very narrow linewidths arising from the reduction of radiation and Ohmic losses [14,34,35,36], which can be exploited for the improvement of the sensitivity of plasmonic sensors [37][38][39], or to achieve band edge lasing [40][41][42][43][44][45][46][47].…”

“…The SLR modes couple to the absorption line of emitters, for example organic dye molecules, and reach the strong coupling regime as evidenced by the square root dependence of the Rabi splitting on the emitter concentration as reported by Väkeväinen et al [13]. Strong coupling in such arrays has already led to new coherence, lasing and condensation phenomena [4,5,14,15].…”

“…For this reason, plasmonic resonators perform as nanocavities for quantum optical applications [12]. Importantly, despite of their low quality factor (caused by metal absorption), the small effective volume of SPs give access to an unexplored parametric region of light-matter coupling, not accessible by other photonic technologies [13][14][15].…”
