论文摘要
微波对光学转导已引起了腔光机械界的极大兴趣，作为电动机械系统的具有里程碑意义的应用程序。在这封信中，我们演示了一种新颖的传感器，该传感器首次结合了高频机械运动和微波炉。该系统由3D微波腔和砷化韧带光学晶体组成，该晶体已放置在微波电场中。这使微波腔可以通过压电效应在光力机械晶体中启动Gigahertz频率机械呼吸模式，然后使用电信光学模式读出。砷化甘氨酸光机电晶体是低噪声微波至tecom的良好候选者，因为它先前已在稀释冰箱中冷却至机械基态。此外，3D微波腔体架构自然可以扩展到夫妇到超导量子台并创建混合量子系统。
Microwave to optical transduction has received a great deal of interest from the cavity optomechanics community as a landmark application for electro-optomechanical systems. In this Letter, we demonstrate a novel transducer that combines high-frequency mechanical motion and a microwave cavity for the first time. The system consists of a 3D microwave cavity and a gallium arsenide optomechanical crystal, which has been placed in the microwave electric field maximum. This allows the microwave cavity to actuate the gigahertz-frequency mechanical breathing mode in the optomechanical crystal through the piezoelectric effect, which is then read out using a telecom optical mode. The gallium arsenide optomechanical crystal is a good candidate for low-noise microwave-to-telecom transduction, as it has been previously cooled to the mechanical ground state in a dilution refrigerator. Moreover, the 3D microwave cavity architecture can naturally be extended to couple to superconducting qubits and to create hybrid quantum systems.
