金属反射中光的自旋霍尔效应
Spin Hall effect of light in metallic reflection
摘要：
本文首次测量了空气-金属界面上的光自旋霍尔效应。SHEL是反射光束上的偏振相关的面外偏移。对于具有线性偏振入射光的金属反射的情况，观察到位移的空间和角度变化，并且对于-45/45度偏振是最大的，但是对于纯s偏振和p偏振为零。然而，对于具有圆偏振态的入射光束，仅存在空间离面移位。
英文摘要：
We report the first measurement of the Spin Hall Effect of Light (SHEL) on an air-metal interface. The SHEL is a polarization-dependent out-of-plane shift on the reflected beam. For the case of metallic reflection with a linearly polarized incident light, both the spatial and angular variants of the shift are observed and are maximum for -45/45 deg polarization, but zero for pure s- and p-polarization. For an incoming beam with circular polarization states however, only the spatial out-of-plane shift is present.
