Hollow-core photonic crystal fibers (HCPCFs), a form of optical conveyer belts, have been used to guide particles for many years. However, only the translational motions of a guided particle can be manipulated. In contrast to traditional types, we demonstrate a new form of optical conveyor belts based on a polarization-maintaining hollow-core photonic crystal fiber (PMHCPCF). Because of the constant polarization state in the PMHCPCF, both the translational and rotational motions of a guided particle can be manipulated simultaneously. For the convenience of theoretical simulations and the effortless control of the polarization state in the PMHCPCF, an x-axis linearly polarized beam and an elliptically polarized beam are coupled into the PMHCPCF to form an incoherent dual-beam trap. For a specific guided particle, the orientation of the particle can be manipulated by the polarization state of the x-axis linearly polarized beam and its rotation rate can be manipulated by the polarization state of the elliptically polarized beam. Moreover, we can obtain any orientation and rotation rate at each trapping position by changing the polarization direction and polarization state. This results in a variety of application prospects in the study of chiral molecules, especially in the fields of biology, medicine, chemistry, and polymers.

中空光子晶体纤维（HCPCF）是一种光学传送带，已被用于引导粒子很多年了。但是，只能控制被引导粒子的平移运动。与传统类型相反，我们展示了一种基于保偏空心光子晶体光纤（PMHCPCF）的新型光学传送带。由于PMHCPCF中的极化状态恒定，因此可以同时控制被引导粒子的平移和旋转运动。为方便理论模拟和毫不费力地控制PMHCPCF中的偏振状态，将x轴线性偏振光束和椭圆偏振光束耦合到PMHCPCF中以形成非相干双光束阱。对于特定的引导粒子，可以通过x轴线性偏振光束的偏振状态来控制粒子的取向，并且可以通过椭圆偏振光束的偏振状态来控制粒子的旋转速率。此外，通过改变偏振方向和偏振状态，我们可以在每个陷印位置获得任何方向和旋转速度。这导致手性分子研究的各种应用前景，特别是在生物学，医学，化学和聚合物领域。
