By exciting resonantly a microcavity with a pulsed laser beam, we have observed the in-plane propagation of excitonic cavity polaritons on distances much greater than the wavelength. The initial in-plane wave vector is conserved during several tens of picoseconds showing it is a good quantum number
We present a full analysis of exciton dynamics in a GaAs ฮป/2 bulk microcavity following excitation by ultrafast laser pulses. Coherent dynamics was probed by means of an interferometric technique; beating and dephasing times were studied for various excitation intensities. At high incident power, po
