Abstract
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.
