摘要： An optical fiber preform having a low core noncircularity and eccentricity for producing an optical fiber having an improved polarization mode dispersion, a method for producing the preform, and an optical fiber produced from the preform. The optical fiber preform is produced by the following steps. Diameter-reduced portions 11a and 11b are formed in the vicinity of the ends of the glass pipe 11. A glass rod 12 is inserted into the glass pipe 11. The glass rod 12 is fixed to the glass pipe 11 at the diameter-reduced portion 11a. The glass pipe 11 and the glass rod 12 are heat-unified from the diameter-reduced portion 11b forward to the diameter-reduced portion 11a. The optical fiber preform has a core noncircularity of at most 1.5%. The optical fiber has a polarization mode dispersion of at most 0.15 ps/km1/2 at a wavelength of 1,550 nm.

摘要： A photonic crystal optical fiber made up of an array of conventional hollow core optical fibers is disclosed. The array of optical fibers omits at least one fiber to form a central hollow core. The fiber works on the principle of two-dimensional photonic crystals to confine the radiation in a guided wave within the central hollow core. The fiber has a true photonic bandgap in which radiation of a particular energy or wavelength is totally forbidden, thereby providing a very high reflection coefficient to radiation incident the walls of the central hollow core over a select range of angles. The central hollow core allows for radiation propagation with minimal absorption.

摘要： The invention provides a fiber with continuously changing chromatic dispersion; it limits the quantity of dispersion-compensating fiber needed in a transmission system to compensate the cumulative chromatic dispersion in the line fiber. The fiber has a higher chromatic dispersion at a first end than at the other end, referred to as the second end. The chromatic dispersion varies along the fiber, decreasing over at least a portion of the fiber. At the first end the chromatic dispersion can be of the order of the dispersion of a conventional line fiber, i.e. close to 8 ps/(nm.km). At the second end the chromatic dispersion can have a value of the order of 4 ps/(nm.km). The fiber is used as the line fiber in a transmission system at the beginning of a section between two repeaters. The chromatic dispersion in the vicinity of the first end limits non-linear effects at the beginning of the section; the decrease of the chromatic dispersion in the fiber ensures that at its second end the fiber can be connected to a fiber having lower chromatic dispersion. The fiber can be produced with an index profile in the shape of a rectangle and a ring by varying only the indices, and not the radii.

摘要： An optical device includes, in a predetermined section of an optical fiber, a first functional part having a plurality of Faraday crystal columns that are parallel to each other and almost penetrating perpendicularly to an optical axis of an optical fiber through a core thereof, and a second functional part having a plurality of holes that are parallel to each other and almost penetrating perpendicularly to the optical axis of the optical fiber 1 through the core thereof. A longitudinal direction of the Faraday crystal columns and a longitudinal direction of the holes form an angle of 45 degrees along a plane perpendicular to the optical axis. Thus, the optical device can be realized only by processing the optical fiber.

摘要： The capacity of an optical transmission system can in principle be increased by interleaving two bits streams with orthogonal polarisation states. This requires, in the interleaved bit stream, the bits of one component bit stream to be timed to occur close to midway between the bits of the other component bit stream. Achieving this by adjustment of relative optical path lengths upstream of the interleaver requires control of those lengths to ±200 microns for ±1 ps bit interleaving accuracy. Such precision is awkward to achieve using fusion splicing. Instead, the necessary precision of interleaving accuracy is achieved by trimming a length of birefringent fiber inserted downstream of the interleaving, this fiber oriented to have its principal polarisation planes (principal axes) aligned with the polarisation states of the two bit streams. Employing birefringent fiber with a beat length of 2.5 mm makes adjustment of fiber length for ±1 ps bit interleaving accuracy very readily achievable, being of the order of ±500 mm.
摘要翻译：光传输系统的容量原则上可以通过交错具有正交偏振状态的两比特流来增加。这要求在交错比特流中，一个分量比特流的比特被定时发生在接近另一分量比特流的比特之间的中间位置。通过调整交织器上游的相对光程长度来实现这一点，需要将这些长度控制在±200微米±1 ps位交错精度。这样的精度难以实现使用熔接。相反，交织精度的必要精度通过修剪插入交织下游的双折射光纤的长度来实现，该光纤被定向为使其主偏振面（主轴）与两个比特流的偏振态对准。使用2.5mm的拍子长度的双折射光纤使得光纤长度的调节可以±1ps位交错精度非常容易实现，为±500mm的量级。

摘要： A method of using a beam of ultra-short laser pulses, having pulse durations below 10 picoseconds, to adjust an optical characteristic within an optical medium is provided. The beams would have an intensity above a threshold for altering the index of refraction of a portion of the optical medium. The beams could be selectively applied to the optical medium and any structures formed or existing therein. Thus, the beam could be moved within a waveguide in the optical medium to alter the index of refraction of the waveguide forming any number of different longitudinal index of refraction profiles. The beam could also be moved within the optical medium near the waveguide to alter an effective index of refraction of a signal traveling within the waveguide. The techniques described can be used to improve, alter or correct performance of waveguide-based optical devices, such as arrayed waveguide gratings and cascaded planar waveguide interferometers.

摘要： The present invention relates to a glass article for use as an optical waveguide fiber and more particularly to an optical waveguide fiber, the core of which is doped with a chalcogenide element to significantly increase the refractive index of the core. The subject of this invention is novel doped silica core compositions wherein a portion of the oxygen in the silica is replaced with either sulfur, selenium or tellurium using plasma enhanced chemical vapor deposition (PECVD). These compositions are designed to have higher refractive indices than silica, low coefficients of expansion, high optical transparency, and appropriate viscosity and softening points to make them ideal candidates for use as optical waveguide fibers.
