The fiber clips is a device for holding an optical fiber which is enclosed in the ferrule, adjustment it to the optimum aligning position with respect to the laser diode and fixing it on the substrate of the butterfly-type laser module by the laser welding. It is hard for the extant saddle shaped clips to be manufactured and the result causes the unable mass production and the high cost. Otherwise, the packaging process has caused PWS of laser module, would decay the coupling efficiency of laser module. Aim at the shortcomings, the purpose of this study proceeds to the creative design of the fiber clips with the systematic engineering design and make a set of the manufacturing method by the pressing die to cause automatic mass production in the future. First, identify the basic characteristics based on an analysis of the patents and then get the conditions and trend. Second, find the function needs and elaborate the specification of design. Third, the use of morphological analysis method and design process is formulated to synthesize and evaluate the improving structure. Finally, taking the design cases will develop the embodiment design and prove the propose approach for the design process. Otherwise, it develops an improvement technique and adjustment method for PWS and wishes can reduce or improve the effects of it.
