3M Announces Two New Erbium-Doped Fibers for Operation in C-Band and L-Band.Business Editors Optical Fiber Communications 2002 ANAHEIM, Calif. & AUSTIN, Texas--(BUSINESS WIRE)--March 19, 2002 3M Optical Components today launched two new rare-earth fibers designed with higher gain to enable smaller packaging size and reduced system cost. For use in both erbium-doped optical amplifiers (EDFAs) and amplified spontaneous emission Amplified spontaneous emission (ASE) or superluminescence is light, produced by spontaneous emission, that has been optically amplified by the process of stimulated emission in a gain medium. (ASE (Adaptive Server Enterprise) A relational DBMS from Sybase that runs on Windows NT/2000, Linux and a variety of Unix platforms. ASE is a comprehensive and robust data management product with a long history dating back to the late 1980s. ) sources, 3M's unique core composition and co-doping process allows higher doping doping, in electronics: see semiconductor. Altering the electrical conductivity of a semiconductor material, such as silicon, by chemically combining it with foreign elements. concentrations while maintaining power conversion efficiency. The high erbium erbium (ûr`bēəm) [from Ytterby, a town in Sweden], metallic chemical element; symbol Er; at. no. 68; at. wt. 167.26; m.p. 1,529°C;; b.p. 2,863°C;; sp. gr. 9.05 at 25°C;; valence +3. concentration results in fiber lengths that can be substantially reduced to meet the desired gain. The FS-ER-7A28 erbium-doped fiber is designed for use in the C-Band and the FS-ER-7B28 is designed for L-Band applications. These fibers are manufactured with exacting optical and geometrical uniformity tolerances and very tight control on mode field diameter In fiber optics, the mode field diameter (MFD) is an expression of distribution of the irradiance, i.e., the optical power per unit area, across the end face of a single-mode fiber. . This results in excellent splice performance to industry standard transmission fibers using common fusion splicing Fusion splicing is the act of joining two optical fibers end-to-end using heat. The goal is to fuse the two fibers together in such a way that light passing through the fibers is not scattered or reflected back by the splice, and so that the splice and the region surrounding it are equipment. 3M's dopant dopant Any impurity added to a semiconductor to modify its electrical conductivity. The most common semiconductors, silicon and germanium, form crystalline lattices in which each atom shares electrons with four neighbours (see bonding). process, combined with flexible, state-of-the-art automated manufacturing and strong fiber and material expertise, enables efficient customization of optical properties. To the customer this means design flexibility and decreased lead times on custom fiber.
