We present a time-resolved study of energy relaxation and trapping dynamics of polariton condensates in
a semiconductor microcavity ridge. The combination of two nonresonant, pulsed laser sources in a GaAs
ridge-shaped microcavity gives rise to profuse quantum phenomena where the repulsive potentials created by
the lasers allow the modulation and control of the polariton flow. We analyze in detail the dependence of the
dynamics on the power of both lasers and determine the optimum conditions for realizing an all-optical polariton
condensate transistor switch. The experimental results are interpreted in the light of simulations based on a
generalized Gross-Pitaevskii equation, including incoherent pumping, decay, and energy relaxation within the
condensate
