Role of guided acoustic wave properties in single-mode optical fibre design
TLDR
In this article, several guided acoustic modes are identified to be responsible for the stimulated backward Brillouin scattering (SBBS) in single-mode optical fibres (SMFs), and the dependence of SBBS gain spectra on acoustic properties of SMF is discussed.Abstract:
