    Abstract: An optical fiber amplifier module is disclosed which comprises a signal path locatee between a signal input and a signal output. A WDM coupler and an amplifying gain medium are disposed along the signal path. A pump laser is disposed out of the signal path in a manner that allows a pump signal from the pump laser to reflect off the WDM coupler and enter the signal path. An embodiment utilizing a second WDM coupler and a second pump laser is also disclosed.

    Abstract: A glass optical waveguide preform is formed by chemical reaction of gaseous and/or vaporized ingredients within a glass substrate tube. A reactant feed tube extends into a first end of the substrate tube. One of the reactants flows through the feed tube, and another flows through the annular channel between the feed and substrate tubes. The reactants combine just downstream of the end of the feed tube and react to form particulate material, at least a portion of which deposit in the substrate tube. The output end of the feed tube traverses the substrate tube so that the region of maximum soot deposition moves along the length of the substrate tube. A hot zone traverses the substrate tube in synchronism with the feed tube to sinter the deposited soot.

    Abstract: A thermoplastic filament comprising multiple polymers of differing flow temperatures in a regular geometric arrangement, and a method for producing such a filament, are described. Because of the difference in flow temperatures, there exists a temperature range at which one polymer is mechanically stable while the other is flowable. This property is extremely useful for creating thermoplastic monofilament feedstock for three-dimensionally printed parts, wherein the mechanically stable polymer enables geometric stability while the flowable polymer can fill gaps and provide strong bonding and homogenization between deposited material lines and layers. These multimaterial filaments can be produced via thermal drawing from a thermoplastic preform, which itself can be three-dimensionally printed. Furthermore, the preform can be printed with precisely controlled and complex geometries, enabling the creation of monofilament and fiber with unique decorative or functional properties.
