Abstract
An optical coupling arrangement comprises conventional focusing optics and an anamorphic (i.e., radially non-symmetric) lens positioned at the entrance to the optical fiber. The objective lens focuses the elliptical beam exiting a laser source and the anamorphic lens functions to change the beam mode from elliptical to circular. The positioning of the anamorphic lens at the fiber input (instead of the laser output) reduces the alignment tolerance problems associated with prior art arrangements.
