Acousto-optic scanning spatial-switching multiphoton lithography
International Journal of Extreme Manufacturing, 2023 Nano-3D printing has obtained widespread attention owing to its capacity to manufacture end-use components with nano-scale features in recent years. Multiphoton lithography (MPL) is one of the most promising 3D nanomanufacturing technologies, which has ...

Terahertz Response of Acoustically-Driven Optical Phonons [PDF]
, 2010 The manipulation of TO-phonon polaritons and the terahertz (THz) light field associated with them by means of an ultra-sound acoustic wave is proposed and illustrated by calculating the TO-phonon-mediated THz response of acoustically-pumped CuCl and TlCl

Composite acousto-optical modulation
Optics Express, 2022 We propose a composite acousto-optical modulation (AOM) scheme for wide-band, efficient modulation of CW and pulsed lasers. We show that by adjusting the amplitudes and phases of weakly-driven daughter AOMs, diffraction beyond the Bragg condition can be achieved with exceptional efficiencies.

Superconducting acousto-optic phase modulator
Optics Express, 2021 We report the development of a superconducting acousto-optic phase modulator fabricated on a lithium niobate substrate. A titanium-diffused optical waveguide is placed in a surface acoustic wave resonator, where the electrodes for mirrors and an interdigitated transducer are made of a superconducting niobium titanium nitride thin film.

Ultrasound-modulated optical tomography for thick tissue imaging [PDF]
, 1995 Continuous-wave ultrasonic modulation of scattered laser light has been used to image objects in tissue-simulating turbid media for the first time. We hypothesize that the ultrasound wave focused into the turbid media modulates the laser light passing ...
