    Abstract

    Polariton condensation in the yellow part of the visible spectrum from a planar organic semiconductor microcavity containing the molecular dye bromine-substituted boron-dipyrromethene is observed. This study provides experimental fingerprint of polariton condensation under nonresonant optical excitation, including the nonlinear dependence of the emission intensity and wavelength blueshift with increasing excitation density, single excitation pulse dispersion imaging, and real space interferometry. The latter two allow to visualize the collapse of the energy distribution and the long-range coherence of the polariton condensate.
