Abstract: An optical switching assembly selectively connects an optical source and a detector to at least one fiber optic device. The assembly includes first and second groups of optical paths, and first and second optical switches. The first optical switch selectively connects the optical source to one end of the first group of optical paths, and the second optical switch selectively connects the detector to the one end of the second group of optical paths. The assembly laos includes a plurality of junctions, each having a lead associated therewith, and one or more of the leads are connected to the fiber optic device. The junctions connect the other end of the first group of optical paths and the other end of the second group of optical paths to the lead to facilitate the testing of the fiber optic device.

Abstract: Fused biconical tapered couplers formed from the pulling of heated optical fibers have controllable coupling ratios by dynamically adjusting the heat intensity and pull speed during fabrication. Fiber coupler fabrication begins by arranging two optical fibers, heating the optical fibers using a heat source a predetermined distance from the optical fibers, and pulling the optical fibers at an initial pulling velocity as the heated optical fibers soften. The heat source is moved away from the optical fibers and the pulling velocity is selectively reduced in response to a substantial change in the detected coupling ratio. Changes in the coupling ratio are controlled by selectively reducing the pulling speed and the heat intensity to a point where the pulling of the optical fibers may be halted, and the heat removed, without a substantial change in the detected coupling ratio. The coupling ratio may be monitored at different wavelengths for fabrication of wideband couplers and wavelength division multiplexers.

Abstract: Fiber optic devices are tested using an optical switching assembly having two optical switches and optical junctions, each optical junction connects an optical fiber from each of the switches to an external optical fiber lead. Each switch is connected to an optical device, for example a laser or a detector, and selectively establishes an optical path between the corresponding optical device and one of the junctions. Hence, a fiber optic device may be tested by connecting the ends of the fiber optic device to respective junction leads, and selectively switching the optical paths to determine the different optical characteristics of the fiber optic device. Calibration devices may also be connected to the leads of unused junctions to check for calibration accuracy and to detect variation in optical performance over time.

The fiber optic device includes a device body such as an optical coupler or a multiplexer and optical fibers. Aluminum metal seals are formed on exposed regions of the optical fibers to provide an interface between the optical fibers and an enclosure.

Abstract: Fiber optic devices are manufactured in an automated environment using a combination of clamps to secure the optical fibers and movable gripping devices that transport the optical fiber during the fabrication process while maintaining control of the ends of the optical fibers. An optical fiber from a spool is removed by a despooling arm having a gripping device, and moveable grippers thread the optical fiber into a set of clamps and place the end of the optical fiber in a clamp designed to splice the fiber optic end to a lead of a testing device. The fiber optic device is formed by dynamically controlling the heating and pulling process based on detected coupling ratios, and hermetically sealed while secured within the clamps. The sealed fiber optic device is moved for testing or packaging using a transport arm having a series of clamps to maintain the position of the fiber optic device and the ends of the leads of the fiber optic device.
