ABSTRACT:
This disclosure describes a precision optical fiber connection system buildable with a minimum of precision-made components. Sets of fibers to be mated are contained in V-grooves in respective opposing silicon-etched fiber holders. A lense-sphere is fixedly deployed in the groove next to the end of each fiber. An initial gross positioning of the lense-spheres of the upper fiber holders with respect to their receiving grooves in the lower fiber holder, is achieved by using a cylinder disposed adjacent to the fiber grooves. Tapered sides of the upper holders engage the cylinder to funnel the lense-sphere into their receiving grooves. Also disclosed is a three-point support system for assuring that the opposing fiber groove surfaces remain parallel and do not experience relative rotation.
