摘要:

观察到自旋和光的内禀轨道角动量的相互作用,证明了在圆柱对称各向同性光纤中的空间图案和光学偏振的长度依赖的旋转。当激发具有自旋和内禀轨道角动量的平行和反平行取向(IOAM= $2\hslash$)的两个模式的叠加时,这种旋转发生在直少模光纤中,这是由模式的传播常数的简并分裂引起的。

英文摘要:

Interaction of spin and intrinsic orbital angular momentum of light is observed, as evidenced by length-dependent rotations of both spatial patterns and optical polarization in a cylindrically-symmetric isotropic optical fiber. Such rotations occur in straight few-mode fiber when superpositions of two modes with parallel and anti-parallel orientation of spin and intrinsic orbital angular momentum (IOAM=$2\hslash$) are excited, resulting from a degeneracy splitting of the propagation constants of the modes.
