摘要： Disclosed is a dispersion compensating optical fiber that includes a core surrounded by a cladding layer of refractive index nCL. The core includes at least three radially adjacent regions, a central core region, a moat region having a refractive index nM that is sufficiently lower than nCL such that &Dgr;M≦−0.4%, and a ring region. As the ring region exhibits sufficiently high refractive index at a sufficiently long distance from the outer edge of the moat region, the fiber can exhibit low values of negative dispersion slope at low values of negative dispersion and yet exhibit good bending loss. This ring region is also capable of imparting to the fiber a relatively high cutoff wavelength, so that the present invention is particularly well suited for use in L-band systems. A particularly suitable fiber has an index profile in which that part of the ring region at the transition between the moat and the ring region has a refractive index such that its delta value is close to zero. Also disclosed is a method of forming the fiber of the present invention.
摘要翻译：公开了一种色散补偿光纤，其包括由折射率nCL的包覆层包围的芯。芯包括至少三个径向相邻的区域，中心芯区域，具有足够低于nCL的折射率nM的护城河区域，使得DELTAM <= -0.4％，以及环形区域。由于环形区域在距离护城河区域的外边缘足够长的距离处呈现足够高的折射率，所以在低分散负值下，纤维可以表现出低的负色散斜率值，并表现出良好的弯曲损耗。该环形区域还能够赋予纤维相当高的截止波长，使得本发明特别适用于L波段系统。特别合适的纤维具有折射率分布，其中在护环和环区之间的转变处的环区的那部分具有折射率使得其δ值接近于零。还公开了形成本发明的纤维的方法。

摘要： An optical fiber and method of making, wherein the optical fiber alternates between regions having different diameters along its length, wherein the refractive index of said blank and the diameters of said fiber are chosen to result in a fiber having alternating regions of positive and negative dispersion at a wavelength which is greater than 1480 nm, yet preferably has a low net dispersion and dispersion slope. A preferred such profile consists of a core region surrounded by a cladding region, said core region comprised of an central core region which is updoped with respect to said cladding region, said central core region surrounded by a moat region which is downdoped with respect to said cladding region, and said moat region is surrounded by an annular ring region which is updoped with respect to said cladding region. In addition, a family of profiles is presented which may be used to produce very low dispersion slope fibers. When used in conjunction with alternating positive and negative dispersion regions, lower net dispersion slope can be achieved. Alternatively, the family of profiles is useful in conventional WDM applications.

The refractive index profiles of waveguide fibers in accord with the invention are disclosed and described. These index profiles provide a waveguide fiber having negative total dispersion and negative total dispersion slope so that a standard waveguide fiber is compensated over an extended wavelength range.

摘要： A pulse-reshaping optical fiber having a core with refractive index nc surrounded by a cladding layer, the diameter of the core changing monotonically along the length of the fiber. The core includes a central region having a maximum refractive index n1 and a moat region disposed radially adjacent to the central region. The moat region has a minimum refractive index n2 which is sufficiently low that the index delta &Dgr;2 of the moat region with respect to nc is not greater than −0.1%. The moat region affects the change in dispersion with respect to fiber cladding diameter, as well as providing the pulse-reshaping fiber with low dispersion versus wavelength slope. The pulse-reshaping fiber is particularly useful in association with optical transmission systems where high transmission rates and narrow pulse widths are desired, including components such as high pulse rate wavelength-division-multiplexers (WDMs) and optical regenerators.
