PROBLEM TO BE SOLVED: To provide a method of manufacturing a terminal of an optical fiber with a lens, which allows an optical axis to be adjusted very easily by giving the same diameter as an optical fiber to the lens provided in the end of the optical fiber. SOLUTION: The front end part of a coreless fiber 1 is formed into a desired radius of curvature so as to function as a lens having the same diameter as an SMF 2, by manufacturing the terminal of an optical fiber with the lens through; a splicing step for fusion splicing the coreless fiber 1 to the end of the SMF 2; a cutting step of cutting the coreless fiber 1 into a fixed length after slicing; a grinding step of grinding the cut end face at a grinding angle corresponding to 3/4 diameter of the SMF 2 and grinding it into a conical shape having a prescribed radius of curvature; and a thermofusion step of shaping the ground surface by thermofusion for a prescribed time after grinding. Thus the method of manufacturing the terminal of an optical fiber with the lens is provided which allows an optical axis to be adjusted very easily. COPYRIGHT: (C)2004,JPO&NCIPI |
