Abstract

A fiber optic device and a method of assembling the fiber optic device to provide at least four degrees of adjustment for an optical beam transported between an optical fiber and bulk optics in an optical device package. At an opening in the wall of the optical processor package, a washer-like structure allows initially adjustable contact at a flat surface thereof and at a spherically curved surface thereof. One of the surfaces bears against the wall about the opening and the other surface bears against a contact feature of a connecting assembly, typically a pre-assembled collimator assembly, that holds a termination portion of the optical fiber. Translational adjustment is made at the flat surface and tilting adjustment is made at the curved surface before final attachment at both surfaces. The fiber optic device is thus aligned with the optical device package and, through that package, can be aligned with another connecting assembly that is initially fixed in place at another opening of the optical device package. Circumferential tapers are provided at appropriate ones of the surfaces, the wall, and the contact feature to facilitate adhesive flow for final attachment.
