论文摘要
在本文中,我们展示了一种使用基于基于相位纯液体晶体的设备在硅硅显示屏上创建具有实时可编程半径,拓扑电荷,极化顺序和位置的多个独立准完美的矢量涡流梁。我们达到了多达7个独立梁的同时产生,拓扑电荷从-3到3,并发现了模拟的相位与测量的相位和极化结构之间的一致性。此外,我们使用了相同的方案来增强单光束的焦点深度,从而产生了在传播过程中保留其性能的“管”梁。
In this paper we show a method for creating multiple independent quasi-perfect vector vortex beams with real-time programmable radii, topological charges, polarization orders and position in 3 dimensions, using a device based on a phase-only liquid crystal on silicon display. We achieved the simultaneous generation of up to 7 independent beams, with topological charges from -3 to 3, and found great agreement between the simulated and the measured phases and polarization structures. Additionally, we used the same scheme for enhancing the depth of focus of a single beam, resulting in a "tube" beam that preserves its properties during propagation.
