Abstract :
Summary form only given. We describe measurements in which we time resolve all four Stokes parameters of the four wave mixing (FWM) emission from a GaAs-AlGaAs MQW and, thereby, completely determine the polarization state of FWM signal as a function of time. We show that the time-resolved FWM (TR-FWM) signal is indeed completely polarized (to within the accuracy of our measurements) at each instant of time.
