We explore the generation of anti-Stokes fluorescence from strongly coupled organic dye microcavities following resonant ground-state excitation. observe polariton emission along lower branch, with our results indicating that this process involves a return to exciton reservoir and absorption thermal energy molecules in vibrationally excited ground-state. speculate population "hot" polaritons is enhanced by fact cavity suppresses Stokes-shifted fluorescence, as it energetically located below cutoff frequency cavity.
