我们测量了平面空气-玻璃界面反射光的自旋霍尔效应的自旋相关纳米级位移。在垂直极化的情况下，位移被发现与入射角增加，并随后减少后，类似的48度，而在水平极化的情况下，它的变化迅速附近的布鲁斯特角。对于30度的固定入射角，随着偏振角从0度（水平偏振）接近类似于39度，位移减小到零，然后沿相反方向增加直到90度（垂直偏振）。(C)2009年美国光学学会
We have measured the spin-dependent nanometer-sized displacements of the spin Hall effect of the reflected light from a planar air-glass interface. In the case of the vertical polarization, the displacement is found to increase with the incident angle and subsequently decrease after similar to 48 deg, while in the case of the horizontal polarization, it changes rapidly near the Brewster angle. For a fixed incident angle of 30 deg, the displacement decreases to zero as the polarization angle approaches similar to 39 deg from 0 deg (the horizontal polarization) and then increases in the opposite direction until 90 deg (the vertical polarization).
