摘要： A method for manufacturing an optical fiber preform and an optical fiber preform apparatus are provided which can reduce hydroxyl groups in an optical fiber preform to a sufficient level without requiring any special equipment or operating conditions. When an optical fiber preform is manufactured by the vapor-phase deposition method, the dehydrating treatment is performed on a porous core preform that is obtained by depositing glass microparticles. In this treatment, a dehydrating agent is supplied to a dehydration apparatus through a feeding pipe and a main feeding pipe made of a material having a water permeance factor of 1.0×10−11 g·cm/cm2·s·cmHg or less, thereby manufacturing an optical fiber preform.

摘要： In a fiber laser apparatus that uses a rare earth added fiber as a light amplifying medium of a resonator or amplifier, the rare earth added fiber is a photonic bandgap fiber in which a rare earth element has been added to a core. Moreover, the loss when the rare earth element absorption portion is excluded from the transmission loss in this photonic bandgap fiber is such that the transmission loss in the wavelength of primary Stokes light that is generated by induced Raman scattering is greater than the transmission loss in the wavelength of light that is output by the fiber laser apparatus. According to the present invention, it is possible to provide a fiber laser apparatus that suppresses the generation of Raman light created by induced Raman scattering, and suppresses the amplification of secondary Stokes light, and is able to efficiently amplify the power of the signal light that is the amplification target.

摘要： This invention provides a method for manufacturing an optical glass in order to prevent the deterioration of the burner used in the synthesis of glass particles that form the optical glass, and to obtain a stable quality optical glass. In this invention, the number of residual bubbles with a diameter of 0.3 mm and more is 0.005/cm3 or less per unit volume of the optical glass. Such optical glass is obtained by controlling the temperature of an end face of the burner for glass synthesis during the deposition of the glass particles by regulating the relationship of the flow velocity or the flow volume between an inflammable gas and a combustion-supporting gas.

This optical fiber has an effective core area of 120 μm2 or more in an employed wavelength band selected from the range of 1.53˜1.63 μm, and has a cut-off wavelength that is capable of substantially single mode propagation in the aforementioned employed wavelength band. As a result, it is possible to construct an optical transmission system having excellent transmission characteristics in which nonlinearity is decreased.

摘要： A dehydration-sintering furnace for dehydrating and/or sintering an optical fiber preform for use in production of an optical fiber includes a muffle for accommodating the optical fiber preform, a heater for heating the muffle, and a pressure fluctuation absorbing apparatus connected to the muffle. Since the pressure fluctuation absorbing apparatus is thermally insulated from a room temperature atmosphere or heated, vapor produced in a dehydration-sintering process is prevented from condensing (liquefying) in a pressure fluctuation absorbing apparatus, thereby preventing reduced dehydration effectiveness in the muffle and reduced quality of the optical fiber preform.
