扭曲光的几何相位

Geometric phase for twisted light

Li-Ping Yang

摘要:

即使在没有双折射的情况下,在螺旋光纤中传播的光的偏振矢量也围绕其传播轴旋转。这种旋转通常被解释为自旋为1的光子的Pancharatnam-Berry相位。在这里,我们使用纯粹的几何方法来理解这种旋转。我们发现,类似的几何旋转也存在扭曲光携带轨道角动量(OAM)。相应的几何相位可以应用于基于光子OAM态的量子计算和量子传感。

英文摘要:

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.
