Abstract

A spin polarization separation of reflected light is observed, when a linearly polarized Gaussian beam impinges on an air-glass interface at Brewster angle. In the far-field zone, spins of photons are oppositely polarized in two regions along the direction perpendicular to incident plane. Spatial scale of this polarization is related to optical properties of dielectric and can be controlled by experimental configuration. We believe that this study benefits the manipulation of spins of photons and the development of methods for investigating optical properties of materials.

χ (a) and θ (b) distributions of reflected light observed on the observing plane. To eliminate spatial noise of CCD chip, a mean filtering with 5×5 kernel is performed for every image before the images are used to retrieve polarization distribution. The original sample size is 800×800pixel, with one pixel size of 6.45×6.45μm2. Insets show theoretical prediction of χ and θ distributions when using data acquired through the second experiment and other parameters in our first experiment.
