Improved connectors for optically coupling a fiber optic transmission line and an opto-electronic device electrically interfaced to a substrate. The improved connectors include the opto-electronic device being mounted on the substrate, such as a printed circuit board, and means for mounting the fiber optic transmission line to the substrate such that the operative axis of the opto-electronic device is substantially not coincidental with the light transmission axis of the fiber optic transmission line. The connectors also require light bending means in operative optical association with said opto-electronic device for directing along the light transmission axis of the fiber optic transmission line at least a portion of the light emitted from said opto-electronic device or for directing along the operative axis of said opto-electronic device at least a portion of the light emitted from said fiber optic transmission line. Applicants have discovered that a connector provided in accordance with the present invention overcomes many of the difficulties associated with prior art connectors of this type.

Light bending devices

A Faraday rotator having an optical element and a donut magnet of length 1.0L for generating a magnetic field along the optical axis of the optical element in order to rotate a plane of polarization of polarized light. At each end of the donut magnet of length 1.0L is a tuning magent of a length from about 0.4L to about 0.7L, with each of said tuning magnets generating a magnetic field in a direction opposite to that of the donut magnet.
