摘要： Detachable optical connectors for optical chips and methods of their fabrication are disclosed. In one embodiment, an optical connector includes a ferrule that supports ferrule waveguides. The optical connector further includes a waveguide support coupled to the ferrule and that supports transition waveguides that are optically coupled to the ferrule waveguides. Ends of the ferrule waveguides are exposed at one end of the ferrule to define a first pitch while ends of the second waveguides are exposed at a chip coupling surface of the waveguide support. The transition waveguides provide at least one type of transition for the guided light traveling within the ferrule waveguides to enable either edge coupling, surface coupling or evanescent coupling to chip waveguides of an optical chip. The transition can include a change in mode-field diameter, direction of the guided light, and/or pitch.

摘要： A fiber array unit (FAU) includes a substrate, a cover element, and a plurality of optical fibers each including a splice joint connecting fibers of different mode-field diameters with a recoating material arranged over at least a portion of the fibers overlapping the substrate, wherein stripped portions of the fibers are arranged in grooves between the substrate and the cover element. A method for fabricating a compact FAU includes splicing ends of stripped sections of first and second optical fiber segments of different mode-field diameters, applying a recoating material over at least portions of the stripped sections, positioning portions of stripped sections of the second optical fiber segments in grooves defined in a substrate, and arranging a cover over the grooves. Certain embodiments include stripping recoating material portions of the second optical fiber segments before they are placed in the grooves.

摘要： A bend inducing fiber array unit is provided comprising first and second anti-recovery plates and a V-groove chip. Opposing lateral anti-recovery plates are arranged on opposite sides of the first and second anti-recovery plates. Lateral edges on a common side of the anti-recovery plates are secured to a common face of one of the opposing lateral anti-recovery plates to fix the first and second anti-recovery plates relative to each other. A guided portion of the array of optical fibers is positioned in the fiber accommodating grooves of the V-groove chip and the V-groove chip is secured to the second anti-recovery plate such that the fiber accommodating grooves and a fiber guiding face of the first anti-recovery plate are fixed at a relative angle θ approximating the bend in the array of optical fibers.

摘要： A fiber array unit (FAU) connector includes a support substrate having a rear-end section and an elevated front-end section. The front-end section has a top surface with fiber grooves that support bare glass sections of optical fibers, which have respective fiber end faces that reside at a front end face defined by the front-end section. Two alignment pins reside in parallel alignment pin channels on opposite sides of the fiber grooves. The alignment pin channels terminate at respective front-end recessed surfaces that are axially spaced from the front end face. The alignment pins extend from the alignment pin channels to be even with the front end face. A cover secured to the front-end section holds the bare glass sections of the optical fibers and the alignment pins in place. Alignment sleeves are used to establish pin-to-pin alignment of confronting FAU connectors.
