Abstract :
We modulate strong coupling in a GaAs/AlGaAs microcavity by transiently decoupling exciton and cavity through the optical Stark effect induced by intense, red-detuned laser pulses. Pulses longer (1500 fs) and shorter (225 fs) than the Rabi cycle time of 500 fs yield distinctly different line shapes.
