Abstract: An optical ferrule comprises first and second compound stop features respectively disposed at opposing sides of the optical ferrule. Each compound stop feature has upper and lower contact surfaces. The lower contact surface is offset below the mating surface of the optical ferrule along a thickness axis perpendicular to the mating surface. The upper contact surface is offset above the mating surface along the thickness axis. The lower contact surface is offset forward from the upper stop surface along a mating direction of the optical ferrule. A connecting surface connects the upper contact surface and the lower contact surface.

Abstract: An optical waveguide propagates an optical mode at a first wavelength along a length of the waveguide. The optical waveguide has an optical core with a substantially polygonal cross-section in a plane substantially perpendicular to the length of the waveguide. The optical core has an index of refraction n1 at the first wavelength. A first optical cladding is disposed adjacent the optical core and has an index of refraction n2 at the first wavelength, n2

Abstract: An optical assembly includes a hermaphroditic cassette comprising a hood that includes a narrower section and a wider section. The narrower and wider sections are separated by slots such that the narrower section fits at least partially within a wider section of an identical mating hood of a mating optical assembly and the wider section receives a narrower section of the mating hood. The hood has first and second stop features configured to engage with second and first stop features of the mating hood. The first stop feature comprises a mating end of the narrower section of the hood and the second stop feature comprises a stop surface disposed within the wider section of the hood. Engagement of the stop features of the hood with stop features of the mating hood is configured to stop relative translational movement of the hood and the mating hood along the mating axis during mating.

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.

Abstract: Each optical cable includes an array of at least one optical waveguide and at least one optical ferrule attached to the array of optical waveguides. The housing includes a first housing portion and a second housing portion engaged with the first housing portion. The second housing portion comprises at least one carrier and one frame. The carrier and frame of the second housing portion are configured to support the one or more optical cables. The first housing portion and the second housing portion are configured such that mechanical engagement of the first housing portion with the second housing portion moves the carrier relative to the frame. Movement of the carrier relative to the frame causes a bend in each optical waveguide and rotation of each ferrule. The bend provides a predetermined spring force of the optical waveguides at a predetermined angle of the ferrule.

Abstract: An optical ferrule has a different thermal expansion coefficient than a substrate to which a optical device is mounted, the ferrule optically coupling the device to one or more optical fibers. The optical ferrule includes and/or a cradle in which the ferrule is mounted include lateral and longitudinal engagement feature that ensure alignment with the optical device at an operating temperature, the ferrule expanding relative to the substrate when transitioning to the operating temperature.

Abstract: A connector has a first magnetic member proximate an opening of the connector. A door of the connector has a gate with a peripheral shape conforming to a shape of an opening of the connector. A pivot of the door rotatably engages with the at least one pivot attachment of the housing on a pivot axis that extends across the gate. A protrusion of the door extends from the pivot axis away from the gate. The protrusion includes a second magnetic member. The first and second magnetic members cause the gate to block the opening in an unmated configuration of the connector.
