a, AP resonance detected with σ− and σ+polarization when the system has been initialized with holes in the K+ valley by applying a finite magnetic field. b, AP resonance detected with σ− and σ+ polarizations after resonant, σ−-polarized excitation with 120 nW excitation power. The vertical dashed lines indicate the optical spot in which the optical spin orientation has been performed.
