“…The simulated results have shown that the customized all-glass LMA-PCF could be operated in the broadband near-infrared range with a stably high focusing efficiency (~70%) and large focal length (~300 μm), which has greatly improved the focusing performance of in-fiber metalens. Besides the PCF as the substrate for integrating the flat metalens, single-mode fibers have also been selected as an appropriate candidate for saddling the metalenses to achieve the short or long-distance focusing of fiber guided mode in either visible band or the near-IR range [ 47 , 48 , 49 , 50 , 51 , 52 , 53 ], which is more approachable for the practical applications in the long-haul optical communication systems. Besides the extensive study of the focusing proprieties for this kind of fiber metalens, it has been found that the numerical aperture (NA) is also a key factor affecting the performance of optical since a larger NA supports a higher coupling efficiency of optical fiber to be applied to high-power applications.…”

The advent of metasurface technology has revolutionized the field of optics and photonics in recent years due to its capability of engineering optical wavefronts with well-patterned nanostructures at subwavelength scale. Meanwhile, inspired and benefited from the tremendous success of the “lab-on-fiber” concept, the integration of metasurface with optical fibers has drawn particular interest in the last decade, which establishes a novel technological platform towards the development of “all-in-fiber” metasurface-based devices. Thereby, this review aims to present and summarize the optical fiber-integrated metasurfaces with the current state of the art. The application scenarios of the optical fiber metasurface-based devices are well classified and discussed accordingly, with a brief explanation of physical fundamentals and design methods. The key fabrication methods corresponding to various optical fiber metasurfaces are summarized and compared. Furthermore, the challenges and potential future research directions of optical fiber metasurfaces are addressed to further leverage the flexibility and versatility of meta-fiber-based devices. It is believed that the optical fiber metasurfaces, as a novel all-around technological platform, will be exploited for a large range of applications in telecommunication, sensing, imaging, and biomedicine.
