Acousto-optic ptychography [PDF]
Optica, 2021 Acousto-optic imaging (AOI) enables optical-contrast imaging deep inside scattering samples via localized ultrasound-modulation of scattered light. While AOI allows optical investigations at depths, its imaging resolution is inherently limited by the ultrasound wavelength, prohibiting microscopic investigations. Here, we propose a computational imaging

Acousto-optic holography for micrometer-scale grid patterning of amplified laser pulses with single-pulse accuracy [PDF]
, 2022 Many optical systems use acousto-optics for fast steering of light. However, acousto-optic (AO) light diffraction permits manipulation and shaping of light fields in a much broader sense including holography.

The Journal of the Acoustical Society of America, 2022 Acousto-optic sensing is based on the interaction between sound and light: pressure waves induce density variations, which, in turn, alter the way light propagates in air. Pressure fields are, thus, characterized by measuring changes in light propagation induced by pressure waves.

Acousto-Optic Modulation in Ambient Air [PDF]
, 2023 Control over intensity, shape, direction and phase of coherent light is a cornerstone of 20 photonics. Modern laser optics, however, frequently demands parameter regimes where either the wavelength or the optical power restricts control e.g.

Acousto-optic modulation of a wavelength-scale waveguide [PDF]
, 2020 We demonstrate a collinear acousto-optic modulator in a suspended film of lithium niobate employing a high-confinement, wavelength-scale waveguide. By strongly confining the optical and mechanical waves, this modulator improves by orders of magnitude a ...
