Abstract

Non-silica fibers made of nonlinear glass materials such as bismuth, chalcogenide and tellurite glass could provide stimulated Brillouin scattering (SBS) interaction that is 2–3 orders of magnitude larger than that obtained in standard silica fibers. Among them, the tellurite fiber has a unique advantage of low propagation loss as small as 0.02 dB/m, and provides a higher Brilliouin gain as well as damage threshold than that of bismuth and chalcogenide glass fiber. Highly-efficient SBS slow light and fast light were demonstrated in tellurite fiber [1, 2]. We report here tunable all-optical pulse compression and stretching could be achieved by customized doublet Brillouin gain line in a short single-mode tellurite fiber. With the higher Brillouin gain by this highly nonlinear tellurite fiber, this approach has dramatically decreased the fiber length and required pump power than that obtained in standard silica fibers [3].
