Abstract(in Japanese) (See Japanese page)
Abstract(in English) The Brillouin frequency shift and its dependence on strain and temperature have been experimentally investigated in GeO_2-doped optical fibers. The investigation on the effect of GeO_2 concentration demonstrates that the strain (temperature) coefficient decreases by 1.48 % (1.61 %) if the concentration increases by a unit mol percentage. The measurement upon three 8-mol% GeO_2-doped fibers drawn under different tensions from the same preform shows that there is an optimized tension during fiber fabrication to maximize the difference of strain and temperature coefficients.
