论文摘要
结构化的光对现代生物技术和临床实践产生了深远的影响,目前在医学中使用了许多光学系统和激光来治疗疾病。我们演示了一个基于纤维的光学钩手术刀的新概念。亚波长光子钩在具有不对称辐射的形状纤维尖端附近获得。需要使用通常用于医学成像的1550 nm连续波源。侧向特征大小小于半波长的光子钩使用带有金属面膜的半球形纤维尖端实现。通过使用带有形状尖端的4μm直径纤维,在环境空气中进行了突破。在光子钩的计算强度分布和尖端大小之间观察到了良好的相关性。用形状纤维尖端产生的光子钩(易于操纵)对潜在应用显示出深远的好处,例如眼科激光手术,超分辨率显微镜,光刻和材料处理。
Structured light have made deep impacts on modern biotechnology and clinical practice, with numerous optical systems and lasers currently being used in medicine to treat disease. We demonstrate a new concept of fiber-based optical hook scalpel. The subwavelength photonic hook is obtained in the vicinity of a shaped fiber tip with asymmetric radiation. A 1550 nm continuous-wave source, commonly used for medical imaging, has been required. Photonic hook with a lateral feature size less than the half-wavelength is achieved using a hemispherical shaped fiber tip with metallic mask. This breakthrough is carried out in ambient air by using a 4-μm-diameter fiber with a shaped tip. A good correlation is observed between the computed intensity distribution of photonic hook and the tip sizes. Photonic hook generated with a shaped fiber tip, easier to manipulate, shows far-reaching benefits for potential applications such as ophthalmic laser surgery, super-resolution microscopy, photolithography, and material processing.
