Abstract: An optical ferrule adapted to receive and transmit light is described. The optical ferrule includes first and second alignment features for mating with corresponding alignment features of a mating optical ferrule. One of the first and second alignment features may be compressible, expandable or compliant. An optical ferrule having first and second alignment features is described, wherein the ferrule is adapted such that the mating/unmating to/from a corresponding ferrule can be effected along two orthogonal dimensions of the ferrule. Additionally an optical ferrule having first and second alignment features is described, wherein the first and second alignment features are located at substantially different first and second locations/contact regions along the ferrule mating direction; the contact regions may also be offset along the thickness direction of the ferrule.

Abstract: A coupling unit includes a light coupling element comprising an attachment area for receiving and permanently attaching to a plurality of optical waveguides. One or more grooves are provided at the attachment area. Each groove is configured to receive an optical waveguide and defined by a bottom surface, a first region, a second region, and an opening. The first region is defined between the bottom surface and the second region. The first region in cross section has substantially parallel sidewalls separated by a spacing. The second region is disposed between the first region and the opening. A width of the opening is greater than the spacing.

Abstract: The disclosure generally relates to individual optical waveguides, sets of optical waveguides such as optical fiber ribbons, and fiber optic connectors useful for connecting individual optical waveguides or multiple optical fibers such as in optical fiber ribbon cables. In particular, the disclosure provides an efficient, compact, and reliable optical fiber connector that exhibits a low insertion loss for use with multimode optical waveguides. The optical connectors incorporate a unitary light coupling unit combining the features of optical fiber alignment, along with redirecting and shaping of the optical beam.
