    Abstract: An optical ferrule assembly includes a hybrid optical ferrule having a glass portion assembled to a polymeric portion. The polymeric portion includes a groove for receiving and supporting an optical fiber having opposing open front and back ends. A light redirecting member includes an input surface for receiving light from the optical fiber and a light redirecting side. The open back end of the groove and the input surface define a recessed region therebetween. The glass portion includes an optically transparent glass insert disposed in the recessed region conforming in shape to an internal shape of the recessed region. An optical fiber is received and supported in the groove. The optical fiber includes a fiber end laser welded to the glass insert so that a central light ray from the optical fiber propagates through the glass insert before being received and redirected by the light redirecting side.

    Abstract: A unitary optical ferrule is molded to include one or more elements for receiving and securing one or more optical waveguides one or more elements for affecting one or more characteristics of light from the optical waveguide while propagating the light within the ferrule. The optical ferrule also includes one or more first alignment features and one or more second alignment features that, when the ferrule is mated with a mating ferrule, each controls alignment of the ferrule with the mating ferrule along three mechanical degrees of freedom. The surface of the optical ferrule can be divided along the thickness axis into a first section and an opposing second section, wherein the first section of the surface includes the receiving and securing elements, the light affecting elements, and the first alignment features and the second section of the surface includes the second alignment features.

    Abstract: A first optical device is adapted to couple to a second optical device along a coupling direction and includes two spaced apart pairs of leading and trailing pads, such that when the first optical device lands and slides on a landing surface of the second optical device to optically couple to the second optical device, and for each pair of leading and trailing pads, the leading pad prevents any debris on the landing surface from collecting on the trailing pad. Upon full coupling of the first optical device with the second optical device, the leading pads do not make contact with the landing surface. The first optical device may be, for example, an optical ferrule or a cradle having a recess adapted to receive an optical ferrule.

    Abstract: An optical cable subassembly includes one or more optical waveguides, at least light coupling unit comprising a first attachment area permanently attached to the optical waveguides, and at least one cable retainer comprising a second attachment area permanently attached to the optical waveguides and adapted to be installed in a housing. A length of the optical waveguides between the first attachment area and the second attachment area allows a bend in the optical waveguides that provides a predetermined mating spring force at a predetermined angle of the light coupling unit when installed in the housing.

    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.
