Blowup dynamics of coherently driven polariton condensates: Experiment

We report an experimental verification of the recent prediction that sharp transitions between steady states in multistable cavity-polariton systems are mediated by intermode parametric scattering that triggers the accumulation of energy and, hence, lowers the threshold at the cost of extending the transition latency period [S. S. Gavrilov, Phvs, Rev. B 90. 205303 (2014) (/process.php? d=joV9v1bWGIdbycTNUhiC3ooXZitTxVt6t9aFxTyp8qv2WTfwPTpqFA%3D%3D&b=1 ) ]. The time-resolved measurements are performed using a high-Q GaAs microcavity pumped slightly above the lower polariton level at normal incidence.
