We report on the realization of an out-of-equilibrium polariton condensate under pulsed excitation in a one-dimensional geometry. We observe macroscopic occupation of a polaritonic mode with only 3% photonic fraction, and a nature strikingly close to that of a bare exciton condensate. With the help of this tiny photonic fraction, the condensate is found to display ?rst-order coherence over distances as large as 10 microns. Based on a driven-dissipative mean ?eld model, we ?nd that the correlations length is limited by the e?ects of a shallow disorder under non-equilibrium conditions.
