论文摘要
光子钩（pHS）是具有高度浓缩曲面光场的非脱脂光束。自发现以来，pHS总是具有一个单个拐点，因此具有钩状结构。在这项工作中，首次报道了一种具有两个拐点和S形结构（S-PHS）的新型pHS。从理论上讲，我们研究了各种物理参数对S-PHS产生的影响。此外，我们表明具有多个斑块的装饰颗粒可以显着增强S-PHS的曲率和长度。 S-PHS可能在超分辨率成像，次波长微加工，粒子和细胞操作等中具有潜在的应用。
Photonic hooks (PHs) are non-evanescent light beams with a highly concentrated curved optical fields. Since their discovery, PHs always have one single inflection point and thus have a hook-like structure. In this work, a new type of PHs with two inflection points and S-shaped structures (S-PHs) were reported for the first time. We theoretically studied the effects of various physical parameters on the generation of S-PHs. Furthermore, we showed that decorating particles with multiple patches can significantly enhance the curvature and length of the S-PHs. The S-PHs may have potential applications in super-resolution imaging, sub-wavelength micromachining, particle and cell manipulation, etc.
