Abstract

Stimulated Brillouin scattering (SBS) is often considered to be problematic, since it limits optical power in telecom and RF photonics applications. However, the highly efficient and narrowband SBS process also provides unique functionality that can be used for a variety of applications. In this talk, I will present recent work exploiting SBS for applications in distributed fiber sensing and high-resolution spectroscopy. First, I will present work showing how the complex Stokes and anti-Stokes interactions can be used to perform distributed temperature and strain measurements with immunity to cross-talk. To achieve higher sensitivity, we introduced a technique that operates by exciting up to 1000 Brillouin lasing modes simultaneously in a fiber ring cavity. We then showed that modifications to these schemes can enable high-resolution spectroscopy with unique combinations of bandwidth, resolution, and measurement rate.
