We report the development of a superconducting acousto-optic phase modulator fabricated on lithium niobate substrate. A titanium-diffused optical waveguide is placed in surface acoustic wave resonator, where electrodes for mirrors and an interdigitated transducer are made niobium titanium nitride thin film. The device performance evaluated as substitute current electro-optic modulators, with sa...

Tunable acousto-optic spectral filters based on null couplers have been improved by making the coupler more uniform. A new double-pass arrangement further narrows the bandwidth, reduces the sidelobes to -20 dB and doubles the frequency shift,

We present an analytical solution for the acousto-optical modulation of multiply scattered light in a medium irradiated with a train of ultrasound pulses. Previous theory is extended to cases where the ultrasound-induced optical phase increments between the different scattering events are strongly correlated, and it is shown that the approximate similarity relation still holds. The relation bet...

The paper is devoted to investigation of Bragg diffraction of light by ultrasound propagating in media possessing strong anisotropy of acoustic properties. It is shown that acoustic anisotropy of crystals influences on the process of light and sound interaction. In case of Bragg regime of acousto-optic interaction, intensity of diffracted light and frequency bandwidths of diffraction in the cry...
