摘要：
Enhancement of Brillouin scattering signal attenuating along optical fiber due to the inherent propagation loss can extend the sensing range or increase the sensing resolution of Brillouin distributed fiber-optic sensing. In this paper, we demonstrate a scheme to investigate the amplification effect of 980-nm pump on Brillouin gain spectrum in an erbium-doped optical fiber (EDF). The Brillouin Stokes power is exponentially raised with increasing the pump power, indicating that adjusting the pump power can control the Brillouin signal in an EDF. We also show that drastic enhancement of Brillouin signal should be possible by using a high-power 980-nm pump laser.
