我们演示了单模碲酸盐光纤中的受激布里渊放大。在1550 nm处抽运功率为10 mW的100 m碲酸盐光纤中，布里渊增益达到29 dB。利用布里渊增益系数的测量数据，计算了受激布里渊散射（SBS）引起的单位功率和单位长度时延。该碲酸盐光纤的峰值功率为0.09246 ns mW-1 m-1，时延斜率效率为1.75 ns/dB。从布里渊增益特性出发，阐明了碲酸盐光纤用于慢光产生的潜在性能。研究结果表明，碲酸盐光纤是一种很有潜力的布里渊光纤放大器和慢光产生材料。
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.
