Stimulated Brillouin scattering by surface acoustic waves in lithium niobate waveguides [PDF]
Journal of the Optical Society of America B, 2023 We numerically demonstrate that Lithium Niobate on Insulator (LNOI) waveguides may support confined short-wavelength surface acoustic waves that interact strongly with optical fields through backward stimulated Brillouin scattering in both $Z$ and $X ...

Cascaded forward Brillouin lasing in a chalcogenide whispering gallery mode microresonator
APL Photonics, 2022 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.
