We directly measured the spatiotemporal evolution of photoexcited local spins in wires made from a modulation-doped GaAs/AlGaAs quantum well by using a time- and spatially resolved Kerr microscopy. We observed the spatial pattern of spin-up and -down near the case of persistent spin helix (PSH) in [110] wires and the retention of the initial spin state in [110] wires which were designed such that the Dresselhaus and Rashba spin- orbit interaction are nearly equal to each other in magnitude.
