摘要

本文分析了对称幂指数相位涡旋的自修复特性。通过在SPEPV的光路中放置障碍物,我们模拟了受阻碍的SPEPV的传播,并从理论上验证了光束的自修复。我们还探讨了外部因素(如障碍物大小和位置)和内部参数(拓扑电荷l和功率指数n)对阻塞SPEPV自修复效果的影响。此外,还讨论了受阻SPEPV的能量流密度、相似系数、有效自修复距离和衍射效率。结果表明,随着传播距离的增加,SPEPV阻塞区域周围的横向能量流将恢复,并且有效自修复距离随着障碍物尺寸rx的增加而逐渐线性增加。自修复特性使花瓣状SPEPV具有三维捕获微粒的能力。

Self-healing properties of symmetrical power-exponent-phase vortices.

The self-healing properties of symmetrical power-exponent-phase vortices (SPEPVs) are analyzed in this paper. By placing an obstacle in the optical path of SPEPVs, we simulated the propagation of the obstructed SPEPVs and verified the self-healing of the beam theoretically. We also explored the influence of external factors (e.g., obstacle size and position) and internal parameters (topological charge l and power exponent n) on the self-healing effect of obstructed SPEPVs. Furthermore, the energy flow density, similarity coefficient, effective self-healing distance, and diffraction efficiency of the obstructed SPEPVs were also discussed. The results demonstrated that the transverse energy flows around the obstructed region of SPEPVs will recover with the propagation distance increased, and the effective self-healing distance gradually increases linearly with the obstacle size r x increased. The self-healing characteristic gives the petal-like SPEPVs the ability to trap microparticles three-dimensionally.
