Title:
分散補償光導波路ファイバ
Document Type and Number:
Japanese Patent JP3602152
Kind Code:
B2
Abstract:
A silica based dispersion compensating optical waveguide fiber includes a core region and a surrounding clad layer. The core region has a refractive index profile which includes a central core region doped with an index raising dopant having a positive central core region index of refraction with a positive Delta %, surrounded by a core moat region having a negative moat region index of refraction with a negative Delta %. The clad layer has a clad index of refraction, said central core region index of refraction being greater than said clad index of refraction which is greater than said core moat region index of refraction. The fiber has a dispersion Ddcf more negative than -20 ps/nm-km at a given wavelength in the range of 1520nm to 1565nm, an attenuation at the given wavelength in the range of 1520nm to 1565nm less than 1 dB/km with a negative average dispersion slope Sdcf (ps/nm<2>) in the wavelength range of 1520nm to 1565nm, and the dispersion at the given wavelength in the range of 1520nm to 1565nm divided by the attenuation at the given wavelength in the range of 1520nm to 1565nm is more negative than -120 ps/nm-dB.
