In recently, twin photonic nanojets (t-PNJs) generated from two coherent illuminations of a single micro-cylinder is theoretically and experimentally investigated. Herein, we investigate a single micro-cylinder illuminated by two coherent plane waves utilizing finite element method. The shape profiles of the t-PNJs are related to the angles and the polarizations of the incident plane waves for a chosen cylinder. Twin photonic hooks (t-PHs) can be generated at an appropriate incident angles. The curvature degrees of t-PHs can be modulated by phase shift of the two incident waves. Our work present a new approach to generate t-PHs. The t-PHs will provide novel applications in nanolithography and optical trapping.

微圆柱体的两个相干平面波照明产生的双光子钩

最近，从理论上和实验上研究了由单个微圆柱体的两个相干照明产生的双光子纳米喷射 (t-PNJ)。在这里，我们利用有限元方法研究了由两个相干平面波照射的单个微圆柱体。t-PNJ 的形状轮廓与所选圆柱的入射平面波的角度和偏振有关。可以以适当的入射角生成双光子钩 (t-PH)。t-PHs 的曲率可以通过两个入射波的相移来调制。我们的工作提出了一种生成 t-PH 的新方法。t-PHs 将在纳米光刻和光学俘获方面提供新的应用。
