if you are interested in learning how to model stimulated brillouin scattering (sbs) in comsol multiphysics®, then tune into this webinar with guest speaker carl meinhart of numerical design, inc. and the university of california, santa barbara.sbs is commonly observed in long lengths of optical fiber, where the electromagnetic intensity exceeds a critical level and there is sufficient distance for the sbs to accumulate. there has been renewed interest in sbs, as it is now feasible to microfabricate photonic chips that exhibit sbs.in this webinar, we present a multiphysics approach for simulating sbs in the comsol® software. first, optical whispering gallery modes are predicted. next, they are combined with the photoelastic tensor to estimate the 3d electrostrictive stress distribution, which is used to simulate 11-ghz acoustical phonons. finally, the sbs gain is calculated by integrating the overlap modes between the pump photons and acoustic phonons. the results are compared to exp...
