Corning Announces Enhanced Polarization Maintaining Fibers for Specialized Applications; PM fibers optimized with higher numerical aperture and polyimide coating.Business Editors/High-Tech Writers CORNING, N.Y.--(BUSINESS WIRE)--Nov. 20, 2003 Corning Incorporated Corning Incorporated NYSE: GLW is an American manufacturer of glass, ceramics and related materials, primarily for industrial and scientific applications. The company was known until 1989 as Corning Glass Works. (NYSE NYSE See: New York Stock Exchange :GLW GLW Glasgow Airport (UK) GLW Gross Laden Weight GLW Good Lady Wife (Australia) ), the industry leader in specialty optical fiber, today announced the introduction of two new polarization maintaining (PM) optical fibers with higher numerical aperture (NA) and high temperature polyimide Pronounced "poly-ih-mid." A type of plastic (a synthetic polymeric resin) originally developed by DuPont that is very durable, easy to machine and can handle very high temperatures. Polyimide is also highly insulative and does not contaminate its surroundings (does not outgas). coating. These newest additions to Corning's broad specialty fiber portfolio capture emerging technology trends in aerospace, fiber optic gyroscope gyroscope (jī`rəskōp'), symmetrical mass, usually a wheel, mounted so that it can spin about an axis in any direction. When spinning, the gyroscope has special properties. , and sensor markets for improved laser coupling efficiency, as well as deployment in harsh environments. Corning's high NA fibers are optimized with 30% higher NA versus standard fibers and are available in PM.1300 with 125-micron cladding, and PM.850 with 80-micron reduced cladding for miniaturized devices. These highly birefringent An optical property of a material that causes the polarizations of light to travel at different speeds. See dispersion. fibers are designed with excellent dimensional uniformity and low beat lengths for applications including planar waveguides, visible light sensor probes, and Faraday effect devices. Additionally, Corning is introducing polarization maintaining fiber with polyimide coating targeted for high temperature, high pressure applications such as aerospace platforms, radiation analysis, and down-hole geological sensing. Available initially at 1300-nanometer wavelength, Corning's polyimide specialty fiber consists of a 10-micron coating applied over standard 125-um cladding to provide a fatigue resistant PM fiber for use in extreme temperature environments. "Our diverse customer segments range from telecommunications to homeland security to oil exploration," states James Haberstroh, product line manager for Corning Specialty Fiber, "The introduction of the high NA and polyimide PM fibers is part of Corning's ongoing strategy to deliver leading technology to both telecom and non-telecom markets. Over the next year we plan to introduce new specialty fibers at an unprecedented rate." Along with these new products, Corning is announcing enhanced specifications for all polarization maintaining products including shorter beat length range, improved crosstalk, and enhanced fiber geometry. Corning offers a broad range of specialty fibers including bend-insensitive, reduced cladding, 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. doped, and polarization maintaining fiber.
