Acousto-Optics in Lithium Niobate-on-Sapphire
Conference on Lasers and Electro-Optics, 2020We 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.

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 ...

Nonreciprocity of acousto-optic interaction in collinear tunable acousto-optic filters
Applied Optics, 2008The investigation of a nonreciprocal effect for the example of collinear acousto-optic interaction is presented. It is shown that this effect influences the parameters of diffraction and the operation of modern acousto-optic devices, particularly acousto-optic tunable filters (AOTFs), at the frequencies of ultrasound of about 1 GHz and higher.

Acousto-optic image processing
Applied Optics, 2008Acousto-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 ...
