摘要： 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.sup.2 -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.

摘要： An improved formation electrolyte and method for anodizing valve metal anodes used in electrolytic capacitors, particularly for high voltage sintered tantalum powder anode, is described. The anodizing electrolyte composition is comprised of 1) a phosphorus oxyacid and/or its salt, such as phosphoric acid and ammonium phosphate; 2) a weak inorganic acid/salt (such as boric acid, ammonium borate) or a weak carboxylic acid/salt; 3) water; and 4) a protic solvent or a mixture of two or more protic solvents. The weak mono-carboxylic acid/salt has 2 to 7 carbon atoms and the weak di- or poly-carboxylic acid/salt has 3 to 13 carbon atoms. The present electrolytes have high anodizing breakdown voltage capability and the formed dielectric oxides have improved oxide quality including good oxide hydration resistant ability, and result in more stable capacitor performance. These properties are particularly important for critical applications such as implantable cardioverter defibrillators (ICDs). Significantly, this means that fewer capacitors are needed to meet an ICD's operating voltage.

摘要： An oxygen plasma process for treating a dielectric oxide layer, particularly an anodic oxide, subsequent to its incorporation into an electrolytic capacitor is described. The present treatment reduces DC leakage and improves shelf life stability of the resulting capacitor in comparison to anodic oxides treated in a conventional manner. This is important for critical applications such as implantable cardioverter defibrillators where capacitor charging time and charge/discharge energy efficiency are critical.

摘要： A single mode optical waveguide fiber having a relatively large effective area and low dispersion includes a segmented core having at least two segments each defining a radius, a refractive index profile and a relative refractive index percent. The waveguide fiber also includes a clad layer surrounding and in contact with the core and having a relative refractive index. The refractive index profiles are selected to provide total dispersion at a wavelength of about 1550 nm of within the range of about 11 ps/nm-km to about 14 ps/nm-km, and total dispersion slope at a wavelength of about 1550 nm of within the range of about 0.045 ps/nm2-km to about 0.055 ps/nm2-km. The refractive index profiles are further selected to provide an effective area greater than or equal to 60 &mgr;m2, and attenuation at a wavelength of about 1550 nm of less than or equal to 0.22 dB/km.
