Cascaded forward Brillouin lasing in a chalcogenide whispering gallery mode microresonator

We report the first observation of cascaded forward stimulated Brillouin scattering in a microresonator platform. We have demonstrated 25 orders of intramodal Stokes beams separated by a Brillouin shift of 34.5 MHz at a sub-milliwatt threshold at 1550 nm. An As2S3 microsphere of diameter 125 µm with...
