Abstract

There is currently a great deal of interest in the development of 1.3 µm fiber amplifiers. Up to now the majority of cases Pr-doped fluoride fibers have been used in order to achieve high gain characteristics [1,2,3]. But fluoride fibers suffer the number of disadvantages, such as comparatively high level of the required pump powers and also the difficulties of the fabrication of silica-to-fluoride splices. Besides, there is a problem of fluoride fibers' strength and reliability. In this paper we report the results of our experiments using stimulated Raman scattering in the low-loss high-germanium-doped silica fibers for signal amplification in 1.3 µm transmission window.
