    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.

    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: A light coupling unit includes a first major surface comprising one or more substantially parallel first grooves oriented along a first direction for receiving one or more optical waveguides. A second major surface for slidably contacting a mating light coupling unit comprises an optically transmitting window for propagating an optical signal therethrough, and a region of second grooves and lands configured to capture particulate contaminants in the second grooves.

    Abstract: A ferrule (10) has a receiving area for receiving and securing an optical waveguide (20) and an optical element (13) for receiving light from an optical waveguide received and secured at the receiving area and changing at least one of a divergence and a propagation direction of the received light. A plurality of registration features (30, 31, 32, 33, 34) are configured to permit a stacking of the ferrule in a stacking direction such that the ferrules in the stack are aligned relative to each other along a length of the ferrule and along a direction perpendicular to the stacking direction.

    Abstract: Optical connectors are provided for connecting sets of optical waveguides (110), such as optical fiber ribbons to each other, to printed circuit boards, or to backplanes. The provided connectors include a waveguide alignment member (105) for receiving and aligning a plurality of optical waveguides (110) such that central light rays of light exiting the plurality of optical waveguides propagate along a same incident direction (115) in a same incident plane XY. The optical connectors also include a light redirecting side that comprises a plurality of segments (130) forming a row of segments (130a, 130b, . . . ), each segment corresponding to a different optical waveguide. A first segment (130a) redirects light along a first redirected direction (140a) and a second segment (130b) redirects light along a second redirected direction (140b) different from the first redirected direction. Other segments redirect light to either a first redirected direction or a second redirected direction. The light is redirected to two or more rows of optical lenses (150). Also provided is a cable assembly that includes a provided connector and a plurality of optical waveguides permanently attached to the connector.

    Abstract: An optical assembly includes first (102) and second (103) housings configured to move relative to each other. The first housing includes an attachment area (124) configured to permanently attach an optical waveguide (122) and having a facet (634) that optically couples the optical waveguide to the first housing. The first housing further includes an first input/output surface (112) at a non-zero angle to the facet and a light redirecting member (638) optically coupled to change a direction and divergence of light between the facet and the first input/output surface. The second housing includes a second input/output surface (113) facing and optically coupled to the first input/output surface. The first and second input/output surfaces maintain an alignment along a light propagation direction therebetween through a range of motion between the first and second housings. The second housing includes a transmission path configured to convey signals optically received or transmitted via the second input/output surface.
