Abstract:
A method of fabricating an optical module including a laser diode producing light, an optical fiber having an input aperture aligned to receive the light, a ferrule fit around an exterior of the optical fiber, and a platform, the method comprising:providing a weld clip having a pair of substantially parallel vertical walls, each of the vertical walls being connected to a corresponding base wall to form an angle of less than 90 degrees with respect to the corresponding base wall; inserting the weld clip over the ferrule such that the ferrule contacts an inner surface of each vertical wall of the weld clip; grasping the ferrule; moving the optical fiber to initially align the input aperture of the optical fiber to the laser diode to substantially optimize coupling of light from the laser diode into the input aperture; attaching the base walls of the weld clip to the platform such that the vertical walls of the weld clip are drawn away from the ferrule to produce a gap between the ferrule and the vertical walls of the weld clip; realigning the optical fiber to the laser diode to substantially optimize coupling of light into the input aperture; and attaching the weld clip to the ferrule.
