Abstract
We present a time-resolved study of the logical operation of a polariton condensate transistor switch.
Creating a polariton condensate (source) in a GaAs ridge-shaped microcavity with a non-resonant pulsed laser beam, the polariton propagation towards a collector, at the ridge edge, is controlled by a
second weak pulse (gate), located between the source and the collector. The experimental results are
interpreted in the light of simulations based on the generalized Gross-Pitaevskii equation, including
incoherent pumping, decay, and energy relaxation within the condensate.
