Abstract:A hybrid silicon/aluminum nitride waveguide on the silicon-on-insulator platform is proposed to achieve an efficient Brillouin optomechanical interaction. Both intra-opticalmode and inter-optical-mode Brillouin scattering can be achieved. The novel arrangement of symmetric electrodes provides out-of-plane electric fields for piezoelectric materials and the possibility of suspended waveguides and cavities. The piezomechanical interaction coupling strength and the Brillouin optomechanical interaction coupling st… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
