Plasmonic photonic nanostructuring on the end facets of optical fibers may enable extensive applications of the miniaturized devices in sensors. However, the small area on the fiber tips and the large aspect ratio of the fiber body largely restrict direct fabrication, which is apparently the challenge in most of the nanopatterning techniques. Therefore, efficient and easily applicable transfer techniques are more practical for fabricating plasmonic nanodevices on the fiber tips. In this study, we report the fabrication of plasmonic photonic structures on large-area planar substrates, flexibilization of the structures into thin films, and transfer of these films onto the end facets of optical fibers. This strategy enables high-quality functionalization of fiber tips by plasmonic photonic devices, thus providing new approaches for sensor applications.

将等离子光子结构灵活地转移到光纤尖端上，用于液体中的传感器应用†

光纤端面上的等离子光子纳米结构可以使小型化设备在传感器中得到广泛应用。然而，纤维尖端上的小面积和纤维体的高长径比极大地限制了直接制造，这显然是大多数纳米图案技术中的挑战。因此，有效且容易应用的转移技术对于在纤维尖端上制造等离激元纳米器件更为实用。在这项研究中，我们报告了在大面积平面基板上制造等离子光子结构，将结构柔化为薄膜以及将这些膜转移到光纤端面上的过程。这种策略可通过等离子光子设备实现光纤尖端的高质量功能化，
