paper name : Time-reversal symmetry breaking with acoustic pumping of nanophotonic circuits.
I am trying to simulate this kind of acousto-optic coupling in optical structures. To be simple, say a si waveguide,with the aid of acoustic frequency it will create grating on it (acoustic is excited in plane), now say suppose I want optical (external light) to couple inside excited from above. Is it possible to show these kind of full wave simulation (acousto-optic) in comsol. Any helpful suggestion is highly appreciated.
