Paper Abstract

Simple method to increase stimulated Brillouin scattering (SBS) threshold in MCVD fiber based on design with few concentric layers having different compound has been proposed. Two sets of fibers with core consisting of three layers with different alumina and germania concentrations have been fabricated. First set of fibers was designed for Raman amplifiers and had a relatively small mode field area of 23-28 μm2. The second set of fibers was designed for high peak power pulse delivery and had mode area of 225-325 μm2. SBS suppression (as compared to the Ge-doped fibers) was estimated from SBS gain spectra and direct observation of SBS threshold to be more than 6 dB and 3.3 dB for the first and the second set of fibers.
