ABSTRACT:
An optical coupling system for improving the coupling efficiency of an elliptical light beam into optical fiber comprises a cylindrical concave microlens on the end facet of the optical fiber in conjunction with a pair of bulk optic asphere lenses. A method of producing a cylindrical concave microlens according to the invention consists of translating a fine wire across the end facet of an optical fiber so as to create a cylindrical grove.
