摘要： An illumination system generating light having at least one wavelength within 200 nm to 2000 nm range. The system includes a light source and at least one light diffusing optical fiber with a plurality of nano-sized structures (e.g., voids). The optical fiber is coupled to the light source. The light diffusing optical fiber has a core and a cladding. The plurality of nano-sized structures is situated either within said core or at a core-cladding boundary. The optical fiber also includes an outer surface. The optical fiber is configured to scatter guided light via the nano-sized structures away from the core and through the outer surface, to form a light-source fiber portion having a length that emits substantially uniform radiation over its length, said fiber having a scattering-induced attenuation greater than 50 dB/km for the wavelength(s) within 200 nm to 2000 nm range.

摘要： A dispersion compensating optical fiber includes a segmented core having a central core segment, a moat segment and a ring segment. The refractive index profile is selected to provide a total dispersion at 1550 nm of between -114 and -143 ps/nm/km, and a kappa, defined as the total dispersion at 1550 nm divided by the dispersion slope at 1550 nm, of between 96 and 150 nm. Optical transmission systems including the present invention dispersion compensating optical fiber optically coupled to a moderate dispersion single mode transmission fiber having dispersion at 1550 nm of between 5 and 14 ps/nm/km are also disclosed. Example transmission systems preferably exhibit residual dispersion over the C+L wavelength band (1525 to 1625 nm) of less than +/- 20 ps/nm per 100 km of the moderate dispersion transmission fiber and less than +/- 10 ps/nm per 100 km of the moderate dispersion transmission fiber over the C band (1525 to 1565 nm).

摘要： Disclosed is an optical waveguide fiber that simultaneously exhibits large effective area and good resistance to bend induced attenuation, as measured by any of the tests known in the art. The cut off wavelength is controlled to allow single mode operation over a wavelength range that extends from about 1340 nm to 1650 nm. The optical waveguide fiber refractive index profile is simple in design allowing cost effective manufacture.

摘要： An optical transmission system is provided. The system includes a series of consecutive blocks of optical fiber. Each block of the system includes a first, second and third series of spans of optical fiber, where the second series of spans compensates for accumulated dispersion in the first and third series in the wavelength range of transmission. Optionally either the first or third series can be omitted.

摘要： Disclosed are refractive index profiles for total dispersion compensating optical waveguide fibers for use in high data rate, long length telecommunications systems. The optical waveguide fibers in accord with the invention provide substantially equal compensation of total dispersion over a range of wavelengths, thus facilitating wavelength division multiplexed systems. Also disclosed are spans of optical waveguide fiber that include a length of transmission fiber together with a length of the compensating fiber. The spans are joined end to end in series arrangement to form the optical waveguide fiber part of a telecommunication system.

摘要： Disclosed is a dispersion compensating and dispersion slope compensating single mode optical waveguide fiber. 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. A telecommunications link using the fiber in accord with the invention is also disclosed and described. A standard fiber to compensating fiber length ratio in the range of 1:1 to 3:1 is shown to give optimum link performance with respect to limiting non-linear dispersion effects.
