Mechanical degrees of freedom, which have often been overlooked in various quantum systems, have been studied for applications ranging from quantum information processing to sensing. Here, we develop a hybrid platform to manipulate the mechanical degrees of freedom with magnetostrictive interaction and optically through the radiation pressure.
Phonon-based frequency combs that can be generated in the optical and microwave frequency domains have attracted much attention due to the small repetition rates and the simple setup. Via optomechanical or magnetostrictive interaction, we experimentally demonstrate a new type of phonon-based frequency comb in the magnomechanical or optomechanical hybrid system. Our demonstration offers an alternative phononic frequency comb for sensing, timing, and metrology applications.
When coherently coupling the magnomechanical system with an optomechanical system by straightway physical contact, the microwave-to-optical conversion with an ultrawide tuning range of up to 3 GHz can be realized. In addition, we observe a mechanical motion interference effect, in which the optically driven mechanical motion is canceled by the microwave-driven coherent motion. This effect shows that mechanical oscillators can be manipulated with equal facility through both magnonic and photonic channels.
Furthermore, the single excitation level strong coupling between the magnon modes and GHz phonon modes in magnonic films has been proved feasible in theory and the optomechanical coupling will be greatly enhanced by the small mode volume. Thus, this kind of integrated magnomechanical system will provide the tools to manipulate the mechanical degrees of freedom at a quantum level and enable new architectures for quantum information processing to sensing.
