An arrangement for collimating and turning an optical beam utilizing a pair of two-dimensional lenses to separate the collimation into separate one-dimensional operations, while using one of the two-dimensional lenses to also perform the turning operation. A first two-dimensional lensing surface is disposed at the endface of a launching waveguide. This first two-dimensional lensing surface provides collimation along one axis of the system (for example, the X axis). A second two-dimensional lensing surface is provided by introducing a defined curvature to a turning mirror in the system. The curvature of the turning mirror is designed to create collimation (or focusing, if desired) in the orthogonal beamfront (in this case, the Y axis beamfront), while also re-directing the propagating signal into the desired orientation.

Two-dimensional lensing arrangment for optical beam collimation and beam orientation

A module for coupling to a fiber-optic cable includes an optoelectronic assembly that includes a bracket and a metal receptacle. The metal receptacle includes an attachment member operable to releasably connect the receptacle to the bracket, an alignment end operable to receive an alignment device, and a connector end operable to releasably connect to the fiber-optic cable and to orient the cable with the alignment device. The metal receptacle can suppress EMI and can typically withstand higher temperatures than most plastic materials. Thus, when subject to high temperatures, the receptacle typically will not expel gas that can fog a lens or deform. The attachment member allows one to releasably connect the receptacle to an optoelectronic assembly without fixing the receptacle to the assembly with adhesive. Thus, the receptacle can be mounted to an optoelectronic assembly quickly and without an alignment fixture.
