A research team headed by Academician Guo Guangcan and Prof. Dong Chunhua from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) has made progress in designing a magno-optomechanical hybrid system.

Credit: Shen Zhen et al The team developed a hybrid system supporting the coherent coupling between an optomechanical cavity and a magnomechanical cavity though straightway physical contact, achieving a microwave-to-optical conversion. The results were published in Physical Review Letters. Different quantum systems, including rare-earth-ion-doped crystals, superconducting circuits, and spins in yttrium iron garnet (YIG) or diamond, have their unique type of quantum operation. In previous research, the team realized a tunable frequency conversion between microwave and photons utilizing the dynamical Faraday effect in a YIG microsphere. However,…
