    Abstract: PURPOSE: A method for fabricating a large size preform of an optical fiber for dispersion control is provided to reduce the variation of the optical property, and to prevent the shrinking deformation of a deposition tube. CONSTITUTION: An optical fiber for dispersion control (300) comprises a core layer(310) composed of silica, germanium oxides and phosphorus oxides, and a clad layer(320) composed of silica, germanium oxides, phosphorus oxides and Freon. A coating layer(330) is disposed on the periphery of the clad. The silica is a main component of the core and the clad, the germanium oxides is added for adjusting the refraction dispersion, the phosphorus oxides is added for reducing the viscosity difference, and the Freon is added for lowering the refraction. The clad layer is deposited on the inner surface of a deposition tube, and the core layer is deposited on the inner surface of the clad layer. A hollow section remaining in the center of the core layer is filled by heating the deposition tube along the axial direction thereof using a burner. It is possible to achieve the uniform optical property by minimizing the variation of the optical property even when a drawing temperature is increased for drawing the optical fiber for dispersion control from the large size preform. Also, it is possible to lower the core deposition temperature, and to reduce the concentration time.

    Abstract: The invention relates to lasers and fiber optics. An amplifying optical fiber operating at a wavelength in the range of 1000-1700 nm comprises an oxide glass core to provide amplification and at least one oxide glass cladding. According to the invention the core contains oxides of elements selected from the group consisting of silicon, germanium, phosphorus, bismuth, aluminum, gallium at concentration of bismuth oxide of 10-4-5 mol %, concentration of silicon and germanium oxides, taken together or separately, of 70-99.8999 mol %, concentration of aluminum and gallium oxides, taken together or separately, of 0.1-20 mol %, concentration of phosphorus oxide from 0 to 10 mol %, and provides a maximum optical gain at least 10 times greater than the nonresonant loss factor in the optical fiber. An outside oxide glass cladding comprises fused silica. The optical fiber core has an absorption band in the 1000 nm region, pumping to which region provides an increased efficiency of power conversion of pump light into luminescence light in the 1000-1700 nm range as compared to pumping to another absorption bands in which pumping brings about luminescence in the 1000-1700 nm range. The optical fiber emits luminescence in the range of 1000-1700 nm when excited by light with wavelengths in the range of 750-12000 nm and a half-height width of the luminescence band of more than 120 nm, and luminescence band boundaries defined as points in which the luminescence intensity drops twice relative to the intensity in the luminescence band maximum lie within the 1000-1700 nm spectral range.
