Temporal bandwidth of consecutive polariton condensation

Abstract
The advent of organic polaritonics has led to the realisation of all-optical transistors, logic gates, and single photon-switches operating at room temperature. In this Letter, we develop a microscopic theory accounting for thermalisation, vibron-relaxation, and radiative and ballistic polariton losses 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 width and unravel the importance of lateral ballistic losses in defining the upper limit of the temporal bandwidth, reaching ~240 GHz.
