Abstract
A system for automatically aligning optical components without active alignment techniques is provided. Optical components are placed into an alignment sleeve having an opening with a diameter sized to tightly receive optical components. Optical fibers having thermally expanded core ends are used to coupled light within the alignment sleeve. In instances where the optical fibers are offset from the longitudinal axis of the sleeve, means are provided to prevent rotation of an optical fiber tube holding the optical fibers.
