Abstract

Methods and apparatus for a dual-fiber ferrule are disclosed. A hole having a preferably elliptical shape and a size suitable for receiving two bare optical fibers is formed along the axis of symmetry of a retaining member. The elliptically-shaped hole determines the angular position of the center of fiber cores of the optical fibers within the retaining member. The dual-fiber ferrule can be used for forming improved optical connectors. A registration feature on the retaining member of the dual-fiber ferrule used in such connectors allows for passive alignment of the optical fibers of one connector with the fibers of another connector when forming an optical link. The optical link includes two such dual-fiber ferrules and a dual-fiber mating sleeve having a feature for engaging the registration feature of each retaining member. In a further aspect, the dual-fiber ferrule can be used for forming improved photonics packages containing two photonics devices, each of which are in optical communication with one of the optical fibers.
