抄録

We studied photoinduced Kerr effect in cavity polaritons in a semiconductor microcavity by carefully measuring the time-resolved Kerr rotation and ellipticity spectra. The Kerr rotation angle of the microcavity polaritons is a hundred times larger than a conventional single quantum well. A spectral shape analysis of the observed spectra suggests that the photomdeced Kerr effect mainly results from a line broadening of the polarions due to spin-polarized polariton-polaritcm scattering. Enhancement in oscillator strength also contributes to the large rotation angle.
