Abstract
A fiber alignment and retention device having an optical lens with a forwardly directed curved surface molded to a rearward extension having a vee-shaped groove for supporting an optical fiber. An abutment means comprises a vertical stop for positioning the fiber at a focal point of the lens and also includes an abutment gap containing an index matching adhesive for reducing refraction and attenuation of a transmitted optical signal. A heat sensitive shrink sleeve secures the fiber within the vee-shaped groove such that a terminal end of the fiber is aligned with the focal point of the lens. A clamp or spring finger may replace the shrink sleeve, and a first alternative embodiment includes a holding means having a cylindrical shaped rearward extension with longitudinal cutaway sections providing a spring tension for securing the fiber. A second alternative embodiment includes a lens with a rearwardly directed radiused surface for guiding and retaining the fiber. A third alternative embodiment includes a modified abutment means for terminating the optical fiber.
