摘要
完美光学涡旋(POVs)提供了一种使能方案,以解决经典光学涡旋对其所携带拓扑电荷的强依赖性所带来的困境。本文提出并演示了一类具有可控脉冲环轮廓的广义 POVs。特别地,给出了一种在两侧各被两个亮环瓣包围的“绝对”暗 POVs,其沿这些暗脉冲环提供了完美的环形势阱,用于稳定捕获低折射率粒子、细胞或量子气体等。进一步地,演示了几种具有不同脉冲环轮廓的 POVs,包括具有亮环的传统 POVs、上述暗 POVs,以及具有可控脉冲环轮廓的 POVs。该工作为任意重塑完美涡旋的脉冲环轮廓开辟了新可能,这类新型 POVs 将丰富光学涡旋的功能,并因其在光操控、量子与经典光通信、增强光学成像以及新型结构化泵浦激光器等中的潜在应用而备受关注。

备注
There was a serious error in figure S1 and it has been corrected in the second version. Also, figure 4 was improved. I am the first time to use arXiv to upload the preprint version and I thought the replacement would 'replace' completely the first version. Afer replacement, I found the incorrect first version was still avaible for public. I am sorry for this trouble. Thanks
