An Electrically Injected and Solid State Surface Acoustic Wave Phonon Laser
Alexander Wendt, Matthew J. Storey, Michael Miller +6
Surface acoustic waves (SAWs) enable a wide array of technologies including RF filters, chemical and biological sensors, acousto-optic devices, acoustic control of microfluidic flo…
Towards a monolithic platform for coupling superconducting circuits to low-loss microwave phonons in AlScN on 4H-SiC
Yuanchen Deng, William W. Roberts, Sueli Skinner-Ramos +12
The paper presents a monolithic platform that integrates aluminum superconducting microwave resonators on silicon carbide with piezoelectric AlScN layers to enable low‑loss microwa…
Spin-Phonon-Photon Strong Coupling in a Piezomechanical Nanocavity
Hamza Raniwala, Stefan Krastanov, Lisa Hackett +3
We introduce a hybrid tripartite quantum system for strong coupling between a semiconductor spin, a mechanical phonon, and a microwave photon. Consisting of a piezoelectric resonat…
Modulation of Brillouin optomechanical interactions via acoustoelectric phonon-electron coupling
Nils T. Otterstrom, Matthew J. Storey, Ryan O. Behunin +3
Optomechanical Brillouin nonlinearities -- arising from the coupling between traveling photons and phonons -- have become the basis for a range of powerful optical signal processin…
Design of optomechanical transducers for sub-micron resolution ultrasound imaging
Lisa Hackett, Chang Ge, Alex Miera +2
Ultrasound is a noninvasive, real-time, and therefore widely used imaging modality; yet its application in cellular and sub-cellular biology is significantly limited by rapidly inc…
S-band acoustoelectric amplifier utilizing an ultra-high thermal conductivity heterostructure for low self-heating
Lisa Hackett, Xingyu Du, Michael Miller +9
Here we report on an acoustoelectric slab waveguide heterostructure for phonon amplification using a thin AlScN film grown directly on a 4H-SiC substrate with an…
