Abstract
A device for compensating for dispersion that includes a single-mode optical fiber consisting of a core, and a cladding, where the fiber has five section, a first section of a user-definable length; a second section of a user-definable length that is tapered at a user-definable rate to a user-definable diameter; a third section of a user-definable length and user-definable cutoff wavelength that is of a diameter equal to that which the second section was tapered; a fourth section of a length equal to the length of the second section, where the fourth section is tapered at the same, but opposite, rate of taper as the second section to a diameter equal to the diameter of the first section; a fifth section of a length equal to the length of the first section, and where the fiber has a user-definable cutoff wavelength. In a second embodiment, two spatial-mode converters are included with the fiber. In a third embodiment, a core-block is induced in the fiber. In other embodiments, a polarizer and a polarization rotator are included in the previous embodiments.
