    摘要:

    光子纳米喷流是光照射尺寸与波长相当或略大于波长的无损电介质微颗粒,在微颗粒后表面形成的高强度、紧聚焦光束。光子纳米喷流具有大于照射光的强度、最小能够小于衍射极限的光束宽度、传播超出倏势场区域和较强的背向散射等优异特性,在光信号增强、微纳加工与制造、超分辨光学成像、超灵敏捕获和探测等领域具有重要的应用。本文首先介绍了光子纳米喷流的源头和发现,然后对光子纳米喷流的模型描述、喷流理论、形貌特征、实验测量和主要特性进行了阐述,之后调研和讨论了光子纳米喷流的几个重要应用,最后对光子纳米喷流进行了总结和展望。

    Abstract:

    Photonic nanojets (PNJs) are high intense, tightly focused light beams on the shadow side surface of lossless dielectric microparticles when the size of the particles is approximately equal to or slightly larger than the wavelength of the incident light. PNJs exhibit exceptional characteristics, including higher intensity than the incident light, minimum beamwidth less than the diffraction limit, propagation beyond the evanescent field region and strong backscattering. These properties make PNJs crucial in various applications such as optical signals enhancement, micro-/nano- processing and manufacturing, super-resolution optical imaging, ultra-sensitive trapping and sensing, among others. This review article begins by introducing the origins and discovery of PNJs, followed by a description of their modeling, nanojet theory, morphology features, experimental measurements, and key properties. Subsequently, it conducts a survey and discussion of several important applications of PNJs. Finally, the article concludes with a summary and prospects for the future of PNJs.
