Paper Abstract

Our aim is to investigate the use of distributed feedback (DFB) fiber lasers [1] as acoustic sensors. In this paper we will discuss the various contributions to the frequency shifts that make such sensing possible, and compare the theoretical results with preliminary experimental results.
