    Abstract: A fiber-based optical amplifier is assembled in a compact configuration by utilizing a flexible substrate to support the amplifying fiber as flat coils that are “spun” onto the substrate. The supporting structure for the amplifying fiber is configured to define the minimal acceptable bend radius for the fiber, as well as the maximum diameter that fits within the overall dimensions of the amplifier package. A pressure-sensitive adhesive coating is applied to the flexible substrate to hold the fiber in place. By using a flexible material with an acceptable insulative quality (such as a polyimide), further compactness in the final assembly is achieved by locating the electronics in a space underneath the fiber enclosure.

    Abstract: A two-dimensional (2D) optical fiber array component takes the form of a (relatively inexpensive) fiber guide block that is mated with a precision output element. The guide block and output element are both formed to include a 2D array of through-holes that exhibit a predetermined pitch. The holes formed in the guide block are relatively larger than those in precision output element. A loading tool is used to hold a 1×N array of fibers in a fixed position that exhibits the desired pitch. The loaded tool (holding the pre-aligned 1×N array of fibers) is then inserted through the aligned combination of the guide block and output element, and the fiber array is bonded to the guide block. The tool is then removed, re-loaded, and the process continued until all of the 1×N fiber arrays are in place. By virtue of using a precision tool to load the fibers, the guide block does not have to be formed to exhibit precise through-hole dimensions, allowing for a relatively inexpensive guide block to be used.

    Abstract: A free space variable optical attenuator (VOA) utilizes a beamsplitter to create tap beams (of both the input signal and the beam-steered output signal) that are directed into monitoring photodiodes. The beamsplitter is configured to exhibit a non-equal splitting ratio such that the tap beams are only a relatively small portion of the input/output beams. The free space configuration eliminates the need for fiber-based couplers, splices and connections to external monitors, as required in prior art VOA monitoring systems. The VOA utilizes a voltage-controlled, MEMS-based tilt mirror to provide beam steering of the propagating, free space beam in a known manner to introduce attenuation (power reduction) in the output signal.

    IPC: G02B6/255

    Abstract: A micro splice protector for a fusion connection between a pair of optical fibers takes the form of a cylindrical sleeve of dimensions similar to that of the fusion splice itself, with an epoxy material used to encase the fusion splice within the sleeve. The sleeve is formed to exhibit an inner diameter only slightly greater than the outer diameter of the fibers, with the length of the sleeve typically formed to be only slightly longer than the stripped end terminations of the pair of fibers being spliced together. The cylindrical sleeve is formed of a rigid (but lightweight) material. An epoxy is injected into the configuration to fill any gaps between the fusion connection and the inner surface of the sleeve. The result is a relatively stiff fusion splice protector that is small in size and well-suited for use in optical packages where space is at a minimum.

The result is relatively stiff fusion splice protector that is extremely small in size and well-suited for use in optical component packages where space is at a minimum.

    Abstract translation: 用于一对光纤之间的熔接连接的微型接头保护器采用与熔接本身尺寸相似的尺寸的圆柱形套筒的形式，其中环氧材料用于将套管中的熔接部分包围。 套筒形成为仅具有稍微大于光纤外径的内径，套筒的长度通常形成为仅比被拼接在一起的一对纤维的剥离端部端部稍长。 圆柱形套筒由刚性但重量轻的材料（例如，不锈钢，熔融二氧化硅）形成，并且将环氧材料注入该构造中以填充熔融连接和套筒内表面之间的任何间隙。 结果是相当僵硬的熔接保护器尺寸非常小，非常适合用于空间最小的光学元件封装。
