A mounting frame system is disclosed that facilitates the mounting of optical connector modules to printed circuit boards. The mounting frame system can include a mounting frame that is configured to attach to a printed circuit board, and is adapted to attach to a connector module. Thus, the mounting frame system can further allow releasable mounting of optical connector modules to the printed circuit board, such that the mounting is achieved in a safe and reliable manner.
摘要:
A method for aligning a ferrule-mounted optical fiber with the optical axis of an electro-optical device, including the following steps: providing an alignment marking with respect to the device in relation to the optical axis; providing an annular receptacle and a tubular alignment pin with a central passageway, having its proximal end slidably fitted in the annulus of the receptacle; aligning the proximal end of the alignment pin with the alignment marking; securing the device to the receptacle; removing the alignment pin from the receptacle; and inserting the ferrule-mounted optical fiber into the receptacle.
摘要:
Glass-based micropositioning systems and methods are disclosed. The micropositioning systems and methods utilize microbumps (40) formed in a glass substrate (12 or 100). The microbumps are formed by subjecting a portion of the glass substrate to localized heating, which results in local rapid expansion of glass where the heat was applied. The height and shape of the microbumps depend on the type of glass substrate and the amount and form of heat delivered to the substrate. The microbumps allow for active or passive micropositioning of optical elements, including planar waveguides and optical fibers. Optical assemblies formed using microbump micropositioners are also disclosed.

Multi-fiber fiber optic connectors (22-26, 40) are described. The fiber optic connectors (22-26) enable direct board-to-board optical communication but do not require data transmission through a backplane (12). In one aspect, a fiber optic connector (40) includes a plurality of optical fibers (42) terminating at proximal and distal ends, and a flexible support (44) configured to hold the optical fibers (42) in an elongated spaced-apart three-dimensional array characterized by insignificant optical coupling between the optical fibers (42). The support (44) has a proximal end terminating at a proximal end face (46) at which the proximal ends of the optical fibers (42) terminate. The proximal end face (46) of the support (44) is sized and arranged to contact a port (88, 90, 112, 114, 134, 136, 164, 166) of an optical device (68, 102, 128, 158) whereupon one or more of the optical fibers (42) couple to the optical device (68, 102, 128, 158) through the port (88, 90, 112, 114, 134, 136, 164, 166). In another aspect, a fiber optic connector (40) includes a plurality of optical fibers (42) formed from a core material with a characteristic refractive index. The optical fibers (42) are embedded in an elongated integral support (44) formed from a flexible cladding material with refractive index that is lower than the refractive index of the core material.
