论文摘要
自成立和实验确认以来,光子钩是可以沿弯曲路径传播的光束,它引起了广泛的关注。在本文中,我们提出了一种新型的结构,该结构是由一个空心的微圆柱和两个不溶性填充液体的Janus形液体柱制成的,用于产生易于调谐特性和长度的光子钩。通过使用有限元方法分析能量流,研究了光子钩的E^2场强度分布特性和形成机理。光子钩的轮廓和性能可以通过旋转空心的微孔或更改光入射角来有效调节。该模型获得了一个衰减长度〜18λ和具有较大焦距〜8λ的光子钩的长光子钩。
The photonic hook, a beam that can propagate along a curved path, has attracted wide attention since its inception and experimental confirmation. In this paper, we propose a new type of structure, which was made by a hollow microcylinder and a Janus-shaped liquid column of two insoluble filling liquids, for producing photonic hook of easily tunable properties and long length. The E^2 field intensity distribution characteristics and formation mechanism of the photonic hook are studied by analyzing the energy flow using the finite element method. The profile and properties of the photonic hook can be effectively tuned by rotating the hollow microcylinder or changing the light incident angle. A long photonic hook with a decay length of ~18λ and a photonic hook with a large focal distance ~8λ are obtained by this model.
