Fabrication of GeO2 Doped Silica Single-mode Fiber
Summary :
Single-mode fibers are prospective candidates for future high-capacity and long distance transmission media. In particular, low loss single-mode fibers, operating around 1.27 µm wavelength, where the material dispersion of silica glass falls to zero, are very attractive because of their huge bandwidth capability. Until now, however, the attainment of very low loss in the long wavelength region has been confined to only multimode fibers. Single-mode fibers with GeO2 -SiO2 glass system, which have the broadest low loss window ant the long wavelength region, were fabricated. The minimum loss of 0.5 dB/km at 1.3 µm wavelength, where dispersion of the fiber is negligibly small, was obtained by suitably designing waveguide parameters and reducing OH contamination. Also, practical structural features and the OH ion behavior are clarified in relation to reduction of OH absorption, which is the major problem in reducing loss at the wavelength of interest.
