The quantum acousto-optic effect in Bose–Einstein condensate

Quantum acousto-optic transducer for superconducting qubits

We propose theory for a reversible quantum transducer connecting superconducting qubits and optical photons using acoustic waves in piezoelectrics. The proposed device consists of an integrated acousto-optic resonator that utilizes stimulated Brillouin scattering for phonon-photon conversion and piezoelectric effect for coupling of phonons to qubits. We evaluate the phonon-photon coupling rate ...

Acousto - Optic Isolator ( Aoi )

Nonlinear effects in acousto-optic imaging.

Acousto-optic (AO) imaging is a promising technique that is able to reveal optical properties in the millimeter range inside scattering media by tagging the photon paths with an ultrasonic beam. To increase both the contrast and the resolution of the AO images, we have explored the possibility of using the nonlinear response of the speckle modulation. Variation of the second-harmonic signal as ...

Applications of In – Fiber Acousto – Optic Devices

Nowadays, in-fiber acousto-optic devices are increasingly used as frequency shifters, multiplexers, modulators, and tunable filters. They can be easily spliced into optical fiber systems, and the consequent low insertion loss, make them an attractive alternative to bulk optics devices. Our group, established at the Institute of Materials Science, Department of Applied Physics, of the Valencia U...

Acousto-optic-assisted diffuse optical tomography.

We introduce and experimentally demonstrate acousto-optic-assisted diffuse optical tomography (DOT) using a holography-based acousto-optic setup. The method is based on probing a scattering medium with a localized acoustical modulation of the phase of the scattered light. The optical properties of the scattering medium are recovered with ultrasound-limited resolution by applying DOT reconstruct...
