Abstract: A single mode optical waveguide fiber having low, non-zero dispersion over a pre-selected wavelength range is disclosed. The refractive index profile of the core is characterized in that the core includes a plurality of distinct regions, each having an index profile, and a radius or width. By adjusting the index profile sizes and shapes of the plurality of core regions, a waveguide fiber may be made having a set of properties tailored for a high performance telecommunication system. In particular, dispersion slope can be maintained less than 0.05 ps/nm -km and absolute magnitude of total dispersion maintained in the range of 0.5 to 3.5 ps/nm-km over a pre-selected wavelength range. The zero dispersion wavelength is outside the pre-selected wavelength range and the cut off wavelength and mode field diameter are controlled to target values.

Abstract: A composite including an inorganic substrate having an outer surface from which pores extend into the substrate and a coating extending over the substrate's outer surface as a substantially uninterrupted layer of carbon. The coating penetrates into the pores of the inorganic substrate. The composite can be made by a process including the steps of contacting an inorganic substrate with a coating and impregnating liquid consisting essentially or wholly of a carbon precursor liquid, treating the inorganic substrate under conditions effective to cure substantially the carbon precursor liquid, and heating the inorganic substrate under conditions effective to convert substantially the cured carbon precursor liquid to carbon.

Abstract: A body is disclosed which is at least about 90% by weight cordierite, and has a coefficient of thermal expansion of less than about 16 x 10 / DEG C from about 25 DEG C to about 1000 DEG C. Also disclosed is a method of fabricating the body. Raw materials are selected to form a nominal composition consisting essentially of in percent by weight about 11.5 to about 16.5 MgO, about 33.0 to about 41.0 Al2O3, and about 46.5 to about 53 SiO2. The raw materials can be a combination of silica and magnesium aluminate spinel, a combination of silica, magnesium aluminate spinel, and a MgO yielding component, or a combination of silica, magnesium aluminate spinel, and a Al2O3 yielding component. The raw materials are provided absent of clay and talc. The raw materials are blended with an effective amount of vehicle and forming aids to impart plastic formability and green strength thereto form a plastic. The raw materials are formed into a green body which is dried and fired at a sufficient temperature for a sufficient time to form the cordierite body.

Abstract: A body is disclosed which is at least about 90% by weight cordierite, has a mean pore size of less than about 10.0 microns, and a coefficient of thermal expansion of no greater than about 9.0 x 10 / DEG C from about 25 DEG C to 1000 DEG C. Also disclosed is a method of fabricating the body. Raw materials are selected to form a composition consisting essentially of in percent by weight about 12 to 16 magnesium oxide, about 35 to 41 aluminum oxide, and about 43 to 53 silica. The raw materials are absent of clay and talc. The magnesium oxide is supplied by a magnesium oxide component having an average particle size of no greater than about 15.0 micrometers in diameter. The aluminum oxide is supplied by an aluminum oxide component having an average particle size of no greater than about 8.0 micrometers in diameter. The composition is capable of forming cordierite in the subsequent firing step. The raw materials are blended with an effective amount of vehicle and forming aids to impart plastic formability and green strength thereto and form a plastic mixture. The raw materials are formed into a green body which is dried and fired. The firing is done by heating to a first temperature of about 1000 DEG C to 1200 DEG C and thereafter raising the temperature at a rate of less than about 100 DEG C per hour to a second temperature sufficient to form cordierite, and maintaining the second temperature for a sufficient time to form the cordierite body.
