The negative-dispersion optical fiber has the following properties at the wavelength of 1550 nm; chromatic dispersion D of not more than -150 ps/nm/km; a dispersion slope satisfying such a condition that a ration thereof (S/D) to the chromatic dispersion D is not less than 2.0 X 10 /nm nor more than 4.7 X 10 /nm; and an effective area of not less than 12 µm . For satisfying these properties, the negative-dispersion optical fiber (200) has, in the order stated from the center toward the outer periphery, a core region (210) of a maximum refractive index n1, a first cladding (221) of a refractive index n2 ( n2), and a third cladding (223) of a refractive index n4 (

摘要： In accordance with the invention, a high speed thermo-optic phase shifter comprises a length of optical waveguide including a waveguiding core of a first material having an index of refraction n1 and a first order temperature dependence nulldn1/dTnull and, optically coupled to the core, a length of a second material having an index n2 preferably greater than the core (n2>n1) and a first order temperature dependence nulldn2/dTnull than the core (nulldn2/dTnull>nulldn1/dTnull). Advantageously, the length of second material is adiabatically tapered at both ends. Upon heating, as by a resistance heater, the second material changes the optical pathlength by an amount predominantly determined by nulldn2/dTnull providing faster switching speed. In a preferred embodiment, the core comprises silica, and the second material comprises silicon to produce switching speeds up to a few hundred MHz.

摘要： An optical transmission line according to the present invention is an optical transmission line which is able to control both the waveform distortion due to the non-linearity phenomenon and the waveform distortion due to dispersion. The optical transmission line is formed by connecting, in series, the first optical fiber (8), of which the dispersion value in the set wavelength band within the 1.5 nullm wavelength band is 6 to 14 ps/nm/km, and the second optical fiber (9), of which the dispersion value in said set wavelength band is null14 to null6 ps/nm/km. The dispersion slopes of the first optical fiber (8) and the second optical fiber (9) are of mutually opposite symbols. Light transmitted from an optical transmitter (11) enters the first optical fiber (8) and light which has been transmitted through the first optical fiber (8) enters the second optical fiber (9). The absolute value of the dispersion in the 1.5 nullm wavelength band of each of the optical fibers (8) and (9) is set to be 6 ps/nm/km or more so as to control the four light wave mixture and said absolute value is set to be 14 ps/nm/km or less so as to control a local dispersion, in order to set at approximately zero, for the entire optical transmission line, both the dispersion value and the dispersion slope in said set wavelength band.

摘要： The specification describes an improved optical fiber design in which the criteria for high performance in a Raman amplified optical system, such as moderate effective area, moderate dispersion, low dispersion slope, and selected zero dispersion wavelength, are simultaneously optimized. In preferred embodiments of the invention, the dispersion characteristics are deliberately made selectively dependent on the core radius. This allows manufacturing variability in the dispersion properties, introduced in the core-making process, to be mitigated during subsequent processing steps.

摘要： An optical fiber suited for dispersion compensation with simultaneous Raman amplification. The fiber has a central core and an index profile that defines successively concentric regions radially outward of the core. The core has a diameter of between 2 and 5 microns (nullm) and a refractive index difference (nulln) with respect to the outer cladding of between 0.012 and 0.035. A trench region adjacent the core is between 2 and 6 nullm wide and has a negative nulln of between null0.015 and null0.003. A ring region adjacent the trench region is between 1 and 5 nullm wide and has a nulln of between 0.001 and 0.015, and an inner cladding surrounding the ring region has a width of between zero and 5 nullm and a nulln of between null0.011 and 0.001. A dispersion slope compensating module (DSCM) including the fiber obtains a relatively high Raman gain with respect to conventional DSCMs that are pumped for Raman amplification.
