Time-resolved Kerr rotation measurements and pump power dependence of spin splitting. (a) Time-resolved Kerr rotation measurements in an asymmetric (001) QW sample for a magnetic field B = 2 T along [110] and [1-10], respectively, at T = 1.5 K. The red lines are the fitting curves. (b) Pump power dependence of spin splitting for T = 1.5 K and B = 2 T. The solid line presents the average value of spin splitting of all pump powers. (c) The spin splitting as a function of magnetic field at 1.5 K. (Color online).
