Chalcogenide glasses (ChGs) have a very wide range of infrared transmittance, extremely high linear and nonlinear refractive index. In this article, research progress on ChG photonic devices based on stimulated Brillouin scattering is reviewed, as well as applications of ChG fibers and waveguides in Brillouin fibers lasers, slow light generation, and microwave photonic filters. Moreover, current problems are summarized, and their potential developments are discussed.
