Direct Visualization of Gigahertz Acoustic Wave Propagation in Suspended Phononic Circuits
Daehun Lee, Qiyu Liu, Lu Zheng +3
We report direct visualization of gigahertz-frequency Lamb waves propagation in aluminum nitride phononic circuits by transmission-mode microwave impedance microscopy (TMIM). Consi…
Electromechanical Brillouin scattering in integrated optomechanical waveguides
Qiyu Liu, Huan Li, Mo Li
In the well-known stimulated Brillouin scattering (SBS) process, spontaneous acoustic phonons in materials are stimulated by laser light and scatter the latter into a Stokes sideba…
Acousto-optic modulation of a photonic crystal nanocavity with Lamb waves in microwave K band
Semere A. Tadesse, Huan Li, Qiyu Liu +1
Integrating nanoscale electromechanical transducers and nanophotonic devices potentially can enable new acousto-optic devices to reach unprecedented high frequencies and modulation…
Nanophotonic cavity optomechanics with propagating phonons in microwave Ku band
Huan Li, Semere A. Tadesse, Qiyu Liu +1
Sideband-resolved coupling between multiple photonic nanocavities and propagating mechanical waves in microwave Ku-band is demonstrated. Coherent and strong photon-phonon interacti…
