    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.

    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.

    Abstract: Optical connectors are provided for connecting sets of optical waveguides (104), such as optical fiber ribbons to each other, to printed circuit boards, or to backplanes. The provided connectors (100) include a housing (110) that has an attachment area (102) for receiving and permanently attaching a plurality of optical waveguides. Additionally, the provided connectors include a light coupling unit (120) disposed in and configured to move with the housing. The provided connectors also include a second attachment area (108) for receiving and permanently attaching to the plurality of optical waveguides that causes each optical waveguide to be bent between the two attachment areas. The provided connectors utilize expanded beam optics with non-contact optical mating resulting in relaxed mechanical precision requirements. The provided connectors can have low optical loss, are easily scalable to high channel count (optical fibers per connector) and can be compatible with low insertion force blind mating.

    Abstract: The disclosure generally relates to sets of optical waveguides such as optical fiber ribbons and embedded optical waveguides, and optical interconnects useful for connecting multiple optical waveguides such as in optical fiber ribbon cables and printed circuit boards (PCBs) having optoelectronic capabilities. In particular, the disclosure provides an efficient, compact, and reliable optical waveguide connector that incorporates microlenses and re-directing elements which combine the features of optical waveguide alignment, along with redirecting and shaping of the optical beam.
