Provided are a metallic micro/nano-structure and an optical fiber having it on the end-facet. The metallic micro/nano-structure comprises of a metallic film and a micro/nano pattern in the metallic film. The micro/nano pattern divides the metallic film into a periodic structure and an embedded defect structure; the defect structure locally breaks the periodicity of the periodic structure; in at least one dimension, the periodic structure has a period T satisfying 0.75&#x3bb;&#x3c;T&#x3c;1.25&#x3bb;, &#x3bb; is a wavelength of a surface plasmon at an interface between the metallic film and a medium; and the surface plasmon resonates within the defect structure and its surrounding area. The optical fiber end-facet device takes the advantages of single-mode optical fiber systems, including stable optical transmission, compact systems and flexible configurations. It achieves high efficiency coupling between fiber guided lightwaves and surface plasmon resonance, using a metallic micro/nano-structure which is a distributed feedback resonant cavity.

An optical fiber having metallic micro/nano-structure on end-facet, and a fabrication method and an application method thereof. The metallic micro/nano-structure is a micro-nano structure resonance cavity on a metallic film, and generates surface plasmon resonance when an optical fiber guided wave is incident. In the fabrication method according to the present invention, the metallic micro/nano-structure on the surface of the substrate is aligned with and is adhered to the end-facet of the optical fiber, and is removed for transferring to the end-facet of the optical fiber. In the application method according to the present invention, the end-facet of the optical fiber is contacted with or moved towards a medium, and a refractive index of the medium is measured by measuring reflection of an optical fiber guided wave by the metallic micro/nano-structure resonance cavity.

The present invention provides a method for fabricating a metallic micro/nanostructure at an optical fiber end-facet by the glue-and-strip method, wherein, firstly a metallic micro/nanostructure is fabricated on a substrate which has a relatively low binding force with it, then an optical fiber end-facet is applied with an adhesive, or a surface of the metallic micro/nanostructure is applied with the adhesive, after that, the optical fiber end-facet and the metallic micro/nanostructure are glued at a predetermined angle, and finally, the adhesive is cured and the optical fiber end-facet and the metallic micro/nanostructure are stripped off the substrate to complete the fabrication. The present invention is based on the idea in the glue-and-strip method that a noble metal is stripped off a weakly bound substrate, and thus demonstrates a new method which enables fabricating a metallic micro/nanostructure at an optical fiber end-facet with high quality, and the process of which is simple, fast, and low cost.
