ABSTRACT:
Methods for aligning an optical fiber with an optical device mounted on a base include: establishing a first position of support near the optical component so as to achieve a substantially optimum alignment, then establishing a second position of support farther way from the optical component so as to refine the alignment; passing the optical fiber through an opening of a support member mounted on the base, moving the optical fiber within the extend of the opening to achieve a substantially optimum alignment, and then fixing the optical fiber to the support; and moving the optical fiber to achieve a substantially optimum alignment with the optical component, then fixing the optical fiber to a support in such a manner that any shift in position that occurs during the fixing is substantially along the optical axis of the optical fiber. Various embodiments of devices that have aligned optical fibers comprise: vertical support members that grip the optical along a distance that is less than or equal to about one-third the diameter of the optical fiber; supports that pivotally support the optical fiber; and supports that provide vertical surfaces orthogonal to the optical axis of the optical fiber for bonding a carrier of the optical fiber.
