The directional resonant secondary emission of a semiconductor microcavity is investigated. Exciting the lower polariton branch, a directional emission on a ring is observed. The coherent emission ring shows a reduction of its angular width for increasing time, a direct evidence for the timeenergy u
We measure the effect of intensity on the homogeneous linewidth of two high finesse semiconductor microcavities in the strong coupling regime using degenerate four-wave mixing. We find that the collisional broadening due to polariton-polariton scattering shows a threshold behaviour with intensity. A
