Acoustic radiation from a superconducting qubit: From spontaneous emission to Rabi oscillations
Vijay Jain, Vladislav D. Kurilovich, Yanni D. Dahmani +6
Acoustic spontaneous emission into bulk dielectrics can be a strong source of decoherence in quantum devices, especially when a qubit is in the presence of piezoelectric materials.…
Acousto-optic modulation of a wavelength-scale waveguide
Christopher J. Sarabalis, Raphaël Van Laer, Rishi N. Patel +4
We demonstrate a collinear acousto-optic modulator in a suspended film of lithium niobate employing a high-confinement, wavelength-scale waveguide. By strongly confining the optica…
Efficient bidirectional piezo-optomechanical transduction between microwave and optical frequency
Wentao Jiang, Christopher J. Sarabalis, Yanni D. Dahmani +5
Efficient interconversion of both classical and quantum information between microwave and optical frequency is an important engineering challenge. The optomechanical approach with…
Piezoelectric transduction of a wavelength-scale mechanical waveguide
Yanni D. Dahmani, Christopher J. Sarabalis, Wentao Jiang +2
We present a piezoelectric transducer in thin-film lithium niobate that converts a 1.7 GHz microwave signal to a mechanical wave in a single mode of a 1 micron-wide waveguide. We m…
The role of resonance and bandgaps in high transducers
Christopher J. Sarabalis, Yanni D. Dahmani, Agnetta Y. Cleland +1
Bandgaps formed in a piezoelectric transducer with large coupling, , qualitatively modify its electrical response. This regime in which electrical loading strongl…
