| Abstract: | Through melting and pulling the end of a fiber into a tapered area, optical fiber transmission and fiber coupling, as well as fiber beam splitting can be realized for the special transmission and coupling characteristic in the tapered area. Optical fiber transmission and fiber coupling between two tapered fibers are analyzed. Also the coupling efficiencies of two tapered fibers versus the vertical distance and the overlap length of two tapered regions of them are analyzed. |
