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: An optical assembly includes a substrate with a plurality of optical waveguides, and a unitary optics array assembled to the substrate. The unitary optics array includes a support portion attached to the substrate, an input surface facing a first waveguide end of each optical waveguide, a redirecting surface, and an output surface. For each optical waveguide, the input surface is configured to receive and transmit a central light ray propagating through and emitted from the first waveguide end of the optical waveguide, and the redirecting surface is configured to receive the central light ray transmitted by the input surface along a first direction and redirect the received central light ray along a second direction different from the first direction, the redirected central light ray exiting the optics array as an output central light ray through the output surface.

Abstract: An optical assembly includes an optical ferrule configured to receive an input light ray through an input location on a major input surface of the optical ferrule along a first direction for coupling to an optical waveguide secured to the optical ferrule, the optical ferrule including a reference location, such that a change in a temperature of the optical assembly causes the input light ray and the input location, but not the reference location, to move respective distances d1 and d2 along a same direction along a same axis, wherein a magnitude of d1-d2 is δ, and a maximum of magnitudes of d1 and d2 is greater than 10 times δ.

Abstract: A fiber optic ribbon is disclosed and includes a plurality of optical fibers extending along a first axis and arranged along an orthogonal second axis at a pitch P. Each optical fiber includes a core surrounded by a cladding surrounded by a buffer, the buffer has a nominal diameter D0 substantially equal to P. The buffer is stripped between a buffer-end location on the fiber and a free end of the fiber to form a stripped section. The buffer is distorted at the buffer-end location, such that at the buffer-end location, a width W of the buffer in the second axis is less than D0.

Abstract: An optical connector (100) comprises one or more optical cables (110) disposed within a housing (120). Each optical cable (110) includes an array of at least one optical waveguide (111) and at least one optical ferrule (112) attached to the array of optical waveguides (111). The housing (120) includes a first housing portion (121) and a second housing portion (122) engaged with the first housing portion (121). The second housing portion (122) comprises at least one carrier (130) and one frame (140). The carrier (130) and frame (140) of the second housing portion (122) are configured to support the one or more optical cables (110). The first housing portion (121) and the second housing portion (122) are configured such that mechanical engagement of the first housing portion (121) with the second housing portion (122) moves the carrier (130) relative to the frame (140). Movement of the carrier (130) relative to the frame (140) causes a bend in each optical waveguide (111) and rotation of each ferrule (112). The bend provides a predetermined spring force of the optical waveguides (111) at a predetermined angle of the ferrule (112).

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: A method of making a patterned layer comprises directing a beam of vaporized material toward a reflector such that the beam of vaporized material impinges an impingement surface of the reflector and is redirected from the reflector through one or more apertures in a shadow mask and onto a deposition substrate to form a patterned material layer.

Abstract: An optical ferrule for transmitting and propagating light having a predetermined wavelength includes a polymeric ferrule body having a fiber alignment feature for receiving an optical fiber, a redirecting side for redirecting light, and an output side window for exiting light therethrough. A multilayer anti-reflection film is disposed on the output side window and includes at least two first layers including titanium oxide and at least two second layers including silicon dioxide. At least one of the two first layers is thinner than an optimum thickness that would minimize reflection at the predetermined wavelength. Heating the optical ferrule at a temperature of about 85 degrees centigrade for at least five hours results in no, or very little, damage to the multilayer anti-reflection film.
