Acousto-Optics in Lithium Niobate-on-Sapphire

Conference on Lasers and Electro-Optics, 2020
We demonstrate nanophotonic waveguides modulated by surface acoustic waves and use them to study the piezoelectric and photoelastic properties of thin-film lithium niobate-on-sapphire.

Acousto-optic modulators

Photoniques, 2023
The laser invention in 1960 has led to the development of acousto-optics and its applications, mainly for deflection, modulation and signal processing. Technical progresses in both crystal growth and high frequency piezoelectric transducers have brought valuable benefits to acousto-optic components ‘improvements and the use of these components in ...

Voltage Controlled Acousto-Electric Self-Oscillating Lithium Niobate SAW Resonator for Integrated Acousto-Optics

Conference on Lasers and Electro-Optics
We demonstrate self-oscillating SAW resonators using InGaAs-TFLN heterostructures for on-chip oscillators and sources of microwave-frequency phonons for acousto-optics.

Multi-Beam Steering and Modulation Using Integrated Acousto-Optics Arrays

Conference on Lasers and Electro-Optics
We present a scalable multi-beam steering and modulation technology using acousto-optic beam steering, enabling simultaneous information transmission to multiple receivers at megabits per second through multiple-input multiple-output free-space optical ...

Acousto-optic supermultispectral imaging

Applied Optics, 1993
An assumption of supermultispectral imaging is presented. The focal point is to encode an object between spatial and spectral information with a tunable bandpass filter, which is called the spatial-spectral encoder. Theoretical and experimental results have verified that the assumption is correct.

Acousto-optics as a field of current interest in research and application

Acousto-Optics and Applications, 2019
Some personal recollections on the acousto-optics as an interesting field of physics and its applications will be shared with the participants in a short welcome address. The consecutive number of the present Spring School on AO and A, 14-th, indicates a

Acousto-optic image processing

Applied Optics, 2008
Acousto-optic processing of images is based on the angular selectivity of acousto-optic interaction resulting in spatial filtration of the image spectrum. We present recent theoretical and experimental investigations carried out in this field. Much attention is given to the analysis of the acousto-optic cell transfer function form depending on the ...

Acousto-optic photonic switch

Optics News, 1989
An acousto-optic architecture is presented to implement a nonblocking space-division switch with O(N) complexity. Signal degradation is minimal so that the switch is suitable for nonregenerative application within optical networks; it is also capable of rapid reconfiguration. Experiments for a 1 x 4 switch show an insertion loss ranging from 4.6 to 5.6

An acousto-optic beamformer

The Journal of the Acoustical Society of America, 2012
There is a great variety of beamforming techniques that can be used for localization of sound sources. The differences among them usually lie in the array layout or in the specific signal processing algorithm used to compute the beamforming output.

Acousto Optics for Cerebral Blood Flow Monitoring

Biophotonics Congress: Optics in the Life Sciences Congress 2019 (BODA,BRAIN,NTM,OMA,OMP), 2019
Acousto-optic sensing, using ultrasound-modulated light in live tissue, enables non-invasive, continuous monitoring of blood flow in the brain. Preclinical and clinical data demonstrate agreement with other modalities for blood flow sensing and its ...
