    Abstract: Optical modules as used in various types of communication systems are formed to include a flexible substrate to support various optical, electronic, and opto-electronic module components in a manner that can accommodate various packaging constraints. The flexible substrate is formed of a polyimide film is known to exhibit excellent electrical isolation properties, even though the films are generally relatively thin (on the order of 10-100 μms, in most cases). The flexible polyimide film is sized to accommodate the constraints of a given package “footprint”; more particularly, sized to fit an open ‘floor area’ within package, allowing for a populated film to be placed around various other “fixed-in-place” elements . The polyimide film is easily cut and trimmed to exhibit whatever topology is convenient, while providing enough surface area to support the affixed components and associated optical fiber traces.

    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 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.
