Abstract: A method of bonding includes using a bonding layer having a fluorinated oxide. Fluorine may be introduced into the bonding layer by exposure to a fluorine-containing solution, vapor or gas or by implantation. The bonding layer may also be formed using a method where fluorine is introduced into the layer during its formation. The surface of the bonding layer is terminated with a desired species, preferably an NH2 species. This may be accomplished by exposing the bonding layer to an NH4OH solution. High bonding strength is obtained at room temperature. The method may also include bonding two bonding layers together and creating a fluorine distribution having a peak in the vicinity of the interface between the bonding layers. One of the bonding layers may include two oxide layers formed on each other. The fluorine concentration may also have a second peak at the interface between the two oxide layers.
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.
