Abstract :
Summary form only given. Direct experimental evidence for the spin-polarization of optically injected ballistic spin currents by coherent one and two photon excitation in unbiased semiconductors is provided via the detection of a phase-dependent movement of the circularly polarized photoluminescence in ZnSe.
