摘要

光子的自旋和轨道角动量在单模光纤中传播过程中会发生扰动,因此,在接收器中,必须调整扰动。对于偏振调节,先前已经开发了偏振控制器。在本文中,我们证明了在存在张力和扭曲等外部效应的情况下,光子不同自由度之间的纠缠不会改变。提出了一种同时调节单模光纤偏振和空间分布的装置。除了修改之外,该设备还可以用于在光纤中产生不同的模式。

All-fiber spatial profile and polarization controller
The spin and orbital angular momentum of photons can perturb during propagation in few mode optical fiber, and hence, in the receiver, perturbations must be adjusted. For polarization adjustment, polarization controllers have been developed previously. In this paper, we show that in the presence of external effects such as tension and tortion, the entanglement between the different degrees of freedom of a photon does not change. A device for simultaneous adjustment of polarization and spatial distribution in few mode fiber is proposed. In addition to modification, this device can also be used to produce different modes in fiber.
