摘要： An improved telecommunications link is provided which includes a dispersion managed fiber with smoothly varying dispersion. The dispersion map may vary sinusoidally or as a sawtooth, for example. The smoothly varying dispersion works well for high data rate transmissions in a return to zero signal format. The dispersion managed fiber with smoothly varying dispersion may be formed by a wide variety of techniques. A method of forming dispersion managed fiber by localized heating or cooling is also provided.

摘要： Optical fiber structures having at least two cores, whether unitary or separable, may be fabricated by controlling the placement of the cores prior to final processing to make the multi-core fiber structure. When the fiber is to be separable, at least two performs are attached, and the attachment height between adjacent canes is controlled to allow separation to be realized (or attachment to be maintained there between) anywhere along the separable multi-core fiber. These canes are then drawn together to form a desired composite fiber, either or both ends of which may be separated to allow for individual manipulation of fiber ends. The separable multi-core fiber may be utilized to fabricate a dual-port or multi-port optical component in which an input and an output (or multiple input/output) fibers are attached to the component, and the exposed distal ends of the separable multi-core fiber are thereafter separated from one another (even after the entire device is assembled and packaged) to provide separated waveguides for pigtailing or splicing to input or output fibers (or other planar or micro-optic components).

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.
