    Abstract: An optical ferrule includes an optical coupling member with a light redirecting element that redirects input light from a waveguide toward an output window. The optical coupling member has a mating surface configured to slidably mate with a mating optical coupling member along a longitudinal axis of the optical ferrule. The optical ferrule also includes at least one stacking member along a longitudinal edge of the optical coupling member. The stacking member has a distal end extending beyond one of the mating surface and a top surface opposed to the mating surface. The stacking member also has a contact surface opposed to the distal end. The contact surface is configured to rotatably interface with a corresponding distal end of a of an adjacently stacked optical ferrule.

    Abstract: An opto-electronic assembly includes a substrate having a plurality of first optical waveguides, a cradle, and a first cover encapsulating at least portions of the first optical waveguides and the cradle. The cradle is bonded to the substrate and defines a pocket therein having an opening. The pocket is configured to receive an optical ferrule through the opening and align the optical ferrule to the first optical waveguides. The first cover includes an aperture exposing the opening of the pocket, such that when the optical ferrule is received in the pocket through the opening and secured therein and a plurality of second optical waveguides are attached to the optical ferrule, the opto-electronic assembly is configured to transfer light between the pluralities of first and second optical waveguides.

    Abstract: An optical connector assembly includes a first optical connector and a second optical connector. The first optical connector includes a first housing, a plurality of first optical fibers, a first cable retainer and a first light coupling unit attached to the plurality of first optical fibers and separated by a first optical fiber length L1. The second optical connector includes a second housing, a plurality of second optical fibers, a second cable retainer and a second light coupling unit attached to the plurality of second optical fibers and separated by a second optical fiber length L2, different from L1. The ratio of L1/L2 is such that, when the first optical connector is mated with the second optical connector, the first light coupling unit and the second light coupling unit rotate relative to the first housing and the second housing, respectively, and mate.

    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: A connector is disclosed that includes a housing and first and second attachment areas located in the housing and spaced apart from each other along the mating direction of the connector. The second, but not the first, attachment area is designed to move relative to the housing. The connector further includes an optical waveguide that is permanently attached to, and under a first bending force between, the first and second attachment areas. The connector also includes a light coupling unit located in the housing for receiving light from the optical waveguide and transmitting the received light to a mating connector along a direction different than the mating direction of the connector. The mating of the connector to the mating connector causes the optical waveguide to be under a greater second bending force between the first and second attachment areas.
