Abstract

The advent of organic polaritonics has led to the realization of all-optical transistors, logic gates, and single photon switches operating at room temperature. In this Letter, we develop a microscopic theory accounting for thermalization, vibron relaxation, and kinetic bimolecular quenching of polaritons and excitons to investigate the intrinsic limitations of the temporal separation of consecutive polariton condensates. We test and verify our theoretical predictions using an optical pump-pump configuration with different pulse widths and unravel the importance of kinetic losses in defining the upper limit of the temporal bandwidth, reaching ∼240GHz.
