Abstract

Brillouin gain spectrum measurement along an optical fiber has recently gained a lot of interests owing to its potentiality for strain monitoring in installed cables [1] and distributed temperature sensing [2]. This measurement requires two lightwaves propagating in opposite directions through the fiber, since Stimulated Brillouin Scattering (SBS) amplification is possible only in the backward direction.
