    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 assembly includes an optical ferrule including a light redirecting member configured to receive light from an optical waveguide along a first direction and redirect the light along a different second direction, the redirected light exiting the optical ferrule at an exit location on a mating surface of the optical ferrule, and a cradle with a mating surface and configured to hold and align the optical ferrule to an optical component, wherein the mating surface of the optical ferrule and the mating surface of the cradle are held together by a magnetic attraction between opposing magnetic elements, wherein the optical ferrule and the cradle, but not the opposing elements, physically contact each other.

    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.

    IPC: G02B6/42

    Abstract: An optical assembly includes an optical ferrule configured to receive light from an optical waveguide and including at least four ferrule alignment features; and a cradle securing the optical ferrule therein and configured to align the optical ferrule to an optical component, the cradle including at least four cradle alignment features configured to make contact or near contact with the at least four ferrule alignment features in a one to one correspondence in at least four corresponding contact regions, such that as a temperature of at least one of the cradle and the optical ferrule changes sufficiently, the corresponding alignment features of the optical ferrule and the cradle slide relative to each other causing the corresponding alignment features of the optical ferrule and the cradle to move to define corresponding traversed regions, such that when extended, the traversed regions of the at least four ferrule alignment features and the at least four cradle alignment features pass within 20 microns of a same first point.

    Abstract: A molded optical ferrule configured to mate with a mating component includes a top surface, a bottom surface opposite the top surface, and a plurality of side surfaces joining the top and bottom surfaces. The plurality of side surfaces includes a plurality of first side surface portions and a plurality of second side surface portions. The first side surface portions make a first angle greater than zero degrees with a thickness direction of the optical ferrule, the first angle assisting in the removal of the optical ferrule from a mold. The plurality of second side surface portions extends outwardly from the first side surface portions and makes a second angle less than the first angle with the thickness direction. When the optical ferrule mates with the mating component, at least some of the second, but not the first, side surface portions contact corresponding side surface portions of the mating component.
