Abstract

This paper compares the performance of axicon phase modulation and Bessel phase modulation in generating perfect optical vortices (POVs). Theoretical analysis and experimental verification show that the POVs generated by axicon phase modulation have energy concentrated on the ring, but the ring radius varies with changes in topological charge. The POVs generated by Bessel phase modulation have side lobes in addition to the main ring, but most of the energy is still focused on the main ring, and the ring radius is relatively stable. Suggestions for generating POVs in different scenarios are provided in the paper.

Axicon相位调制与贝塞尔相位调制在产生完美光学旋涡中的性能比较

本文比较了轴突相位调制和贝塞尔相位调制在产生完美光旋涡方面的性能。理论分析和实验验证表明，轴子相位调制产生的pov能量集中在环上，但环半径随拓扑电荷的变化而变化。贝塞尔相位调制产生的pov除了主环外还存在侧瓣，但大部分能量仍集中在主环上，且环半径相对稳定。本文提出了在不同场景下生成pov的建议。
