论文摘要
在盘绕的光纤中传播的光线的极化向量即使在没有双折射的情况下，也会绕其传播轴旋转。通常，由于自旋1光子的pancharatnam-berry相，通常会解释这种旋转。在这里，我们使用纯几何方法来理解这种旋转。我们表明，携带轨道角动量（OAM）的扭曲光也存在类似的几何旋转。相应的几何相可以应用于基于光子OAM状态的量子计算和量子传感。
Polarization vectors of light traveling in a coiled optical fiber rotate around its propagating axis even in the absence of birefringence. This rotation was usually explained due to the Pancharatnam-Berry phase of spin-1 photons. Here, we use a purely geometric method to understand this rotation. We show that similar geometric rotations also exist for twisted light carrying orbital angular momentum (OAM). The corresponding geometric phase can be applied in photonic OAM-state-based quantum computation and quantum sensing.
