A method of locating the azimuthal positions of the transverse axes of an optical fiber that has a cladding and a core with an elliptical cross section, where the elliptical cross section has a major axis and a minor axis and the optical fiber has a longitudinal axis. The present invention also provides a method of detecting the azimuthal position of an optical fiber from which an interference pattern generated by reflections from a coherent light beam directed onto the optical fiber in a direction transverse to the optical fiber's longitudinal axis changes symmetrically as the fiber is turned in opposite directions about its longitudinal axis. In addition, the invention provides a method to determine which axis of an optical fiber elliptical's core, the major axis or the minor axis, is orthogonally aligned with the coherent HeNe laser beam. Further, the invention provides a method of joining two optical fibers where the transverse axes of the fibers' elliptical cores are aligned with one another or are separated from one another at a specified angular separation. The invention also provides a method of detecting the azimuthal positions indicated above utilizing a programmable electronic device capable of storing, retrieving and processing data.
