摘要

轨道角动量(OAM)光束由于其独特的光学性质和新的自由度,已被应用于各个领域。OAM光束拓扑电荷的检测是其应用的关键步骤。然而,具有大TC的OAM波束的片上排序仍然是一个挑战。本文建立了五个半环形纳米片的Bloch表面波(BSW)结构模型。在两个相邻的OAM状态之间在芯片上获得了135nm的空间间隔。BSW结构可以成功地对TC高达35的OAM光束进行分类,这比使用金属结构(只有7个)要大得多。BSW结构表现出比金属结构更好的OAM分选性能。我们系统地展示了与在金属结构上传播的表面等离子体激元相比,BSW结构的较低衰减如何导致优越的分离能力。此外,可以通过这种方式同时实现具有不同TC的两个OAM波束的排序。我们的结果表明,BSW结构应该是用于具有大TC的OAM排序的优秀解决方案,这有利于集成芯片上设备和光通信中的应用。

On-chip sorting of orbital angular momentum beams using Bloch surface wave structures
Owing to their unique optical properties and new degrees of freedom, orbital angular momentum (OAM) beams have been applied in various fields. Detection of the topological charges (TCs) of OAM beams is the key step for their applications. However, on-chip sorting of OAM beams with large TCs still remains a challenge. In this paper, Bloch surface wave (BSW) structures with five semi-ring shaped nanoslits are modeled. A spatial separation of 135 nm on the chip is obtained between two neighboring OAM states. OAM beams with TCs up to 35 can be successfully sorted by the BSW structures, which is much larger than that using metallic structures (only seven). BSW structures exhibit better OAM sorting performances than metallic structures. We systematically show how the lower attenuation of BSW structures leads to far superior separation ability compared to surface plasmons propagating on metallic structures. In addition, sorting of two OAM beams with different TCs simultaneously can be achieved in this way. Our results reveal that BSW structures should be an excellent solution for OAM sorting with large TCs, which is beneficial for applications in integrated on-chip devices and optical communications.
