Abstract
Embodiments are directed to a microwave-to-optical transducer device. The device includes an anchorage structure that includes a bar extending in a plane and laterally delimiting two voids on each longitudinal side of the bar. That is, the two voids are arranged side-by-side in said plane. The device further includes a piezoelectric beam structured as an optical cavity (e.g., as a 1D photonic crystal cavity), where the beam extends transversally to the bar, parallel to said plane, and is anchored on a resting point on the bar. The beam extends outwardly, beyond the resting point and on each side thereof, so as to overhang each of the two voids. Embodiments are further directed to related microwave circuits, including a microwave-to-optical transducer such as described above and, in particular, to superconducting microwave circuits configured as quantum information processing devices.
