Stimulated Brillouin Amplification in a Tellurite Fiber as a Potential System for Slow Light Generation

Abstract

We demonstrate stimulated Brillouin amplification in a single-mode tellurite fiber. A Brillouin gain of 29 dB is achieved in a 100 m tellurite fiber with a pump power of 10 mW at 1550 nm. Stimulated Brillouin scattering (SBS) induced time delay per unit power and per unit length is also calculated using the measured data of Brillouin gain coefficients. A peak value of 0.09246 ns mW-1 m-1 and a time delay slope efficiency of 1.75 ns/dB are obtained for this tellurite fiber. Potential performance of a tellurite fiber for slow light generation is clarified on the base of Brillouin gain characteristic. Our results show that tellurite fiber is a potential candidate for Brillouin fiber amplifiers and slow light generation.
