光自旋霍尔效应的研究性实验教学

Research-oriented teaching in experiment of spin Hall effect of light

光自旋霍尔效应是由于光子的自旋-轨道相互作用导致自旋相反的光子相互分离的光学效应,极大地丰富了光学研究内涵,成为现代光学的研究前沿和热点.由于光自旋霍尔效应实验与由偏振片、望远镜、显微镜等器件组装的实验相通,因此可以把光自旋霍尔效应的研究成果进行整理,设计制作出适合于本科实验教学的仪器.本文对光自旋霍尔效应的研究进展进行了综述,并介绍了利用所开发的光自旋霍尔效应实验仪可开展的实验类型和进行研究性教学的情况.

The spin-orbit interaction can result in a spatial separation of the left-and right-handed circularly polarized photons,which is termed the spin Hall effect of light(SHEL).The SHEL enriched the content of optics and has become the hotspots in research.Due to the resemblance between the SHEL experimental setup and standard telescope or microscope system,such as the polarizers,telescopes and microscopes,it was probable to develop an instrument for undergraduate teaching based on the achievements of the SHEL.In this paper,we reviewed the research of the SHEL and briefed the type of experiment and the study of teaching using the self-made instrument.
