Abstract: A light coupling element including a groove and a light redirecting member is described. The groove is for receiving and aligning an optical waveguide and incudes an open front end and a back end. The light redirecting member includes an input side for receiving light from an optical waveguide received and supported in the groove and a light redirecting side for changing a direction of light received from the input side. The groove may include a bottom surface extending between the front and back ends of the groove and including a raised bottom surface portion raised upwardly relative to an unraised bottom surface portion. The unraised bottom surface portion of the bottom surface may be disposed between the raised bottom surface portion of the bottom surface and the input side of the light redirecting member. Optical coupling assemblies including the light coupling element and an optical waveguide are described.

Abstract: An optical communication subassembly includes one or more optoelectronic devices, one or more optical elements, and a transceiver light coupling unit. Each optical element is configured to change a divergence of the outgoing light relative to a divergence of the incoming light and is spaced apart from and optically aligned with a corresponding optoelectronic device. The transceiver light coupling unit has a mating surface configured for mating with a connector light coupling unit attached to an optical waveguide. A mating direction of the optical light coupling unit forms an angle with the mating surface of the transceiver light coupling unit such that when the connector light coupling unit mates with the transceiver light coupling unit, the angle between the mating direction of the connector light coupling unit and the mating surface of the transceiver light coupling unit causes the optical waveguide to bend.

Abstract: An optical cable subassembly includes one or more optical waveguides, at least light coupling unit comprising a first attachment area permanently attached to the optical waveguides, and at least one cable retainer comprising a second attachment area permanently attached to the optical waveguides and adapted to be installed in a housing. A length of the optical waveguides between the first attachment area and the second attachment area allows a bend in the optical waveguides that provides a predetermined mating spring force at a predetermined angle of the light coupling unit when installed in the housing.

Abstract: An optical ferrule includes at least one light affecting element configured to affect one or more characteristics of light from an optical waveguide as the light propagates in the optical ferrule, the light affecting element having an input surface. At least one receiving element receives and secures the optical waveguide to the ferrule so that an output surface of the waveguide is optically coupled to the input surface of the light affecting element. A waveguide stop limits movement of the waveguide toward the input surface of the light affecting element when the optical waveguide is installed in the receiving element. A space between the output surface of the optical waveguide and the input surface of the light affecting element is inaccessible to the optical waveguide when the optical waveguide is installed in the receiving element.

Abstract: A hybrid connector includes a connector housing, one or more first connection elements configured to transfer a first type of energy or a fluid, and one or more second connection elements configured to transfer a second type of energy, different from the first type of energy, or the fluid. The first connection elements are rotationally fixed and the second connection elements are configured to rotate around an axis that is substantially perpendicular to a mating axis of the housing

Abstract: A unitary optical ferrule is molded to include one or more elements for receiving and securing one or more optical waveguides one or more elements for affecting one or more characteristics of light from the optical waveguide while propagating the light within the ferrule. The optical ferrule also includes one or more first alignment features and one or more second alignment features that, when the ferrule is mated with a mating ferrule, each controls alignment of the ferrule with the mating ferrule along three mechanical degrees of freedom. The surface of the optical ferrule can be divided along the thickness axis into a first section and an opposing second section, wherein the first section of the surface includes the receiving and securing elements, the light affecting elements, and the first alignment features and the second section of the surface includes the second alignment features.

Abstract: A modular optical connector includes a plurality of coupled optical ferrule support modules. Each optical ferrule support module comprises module connecting features configured to couple each ferrule support module with one or more neighboring ferrule support modules of the plurality of ferrule support modules. One or more optical ferrules are disposed and configured to rotate within the ferrule support module. Each optical ferrule includes a first attachment area configured to attach to one or more optical waveguides. One or more passageways are disposed within the ferrule support module. Each passageway is configured to receive the one or more optical waveguides. The passageway comprises a second attachment area configured to attach to the optical waveguides that are attached to the optical ferrule at the first attachment area. The passageway is dimensioned to constrain the optical waveguides to bend within the housing between the first attachment area and the second attachment area.
