Streszczenie:
We report on the occurrence of strong nonlinear acousto-optic interactions in phoxonic structures, that support, simultaneously, acoustic and optical localized resonant modes, under the influence of acoustic losses. Deploying a detailed theoretical investigation of the acousto-optic coupling in the specific case of a one-dimensional phoxonic cavity, realized by homogeneous SiO2 and Si layers, we demonstrate the possibility for an enhanced modulation of light with sound through multi-phonon exchange mechanisms. A full electrodynamic and elastodynamic multiple scattering approach is employed to

Active light modulation enables precise control over such light properties as intensity, phase, frequency, and polarization. This article examines electrooptic (EO), acousto-optic (AO), and magneto-optic (MO) modulation methods, analyzing their principles, advantages, and limitations for high-speed optical systems. The EO modulation, based on changes in the refractive index under the influence of an electric field, provides ultrafast signal modulation but is sensitive to electromagnetic interference. The AO modulation uses acoustic waves to periodically vary the refractive index, allowing high

Abstract The non-collinear diffraction of Airy light beams on ultrasound in the regime of weak and strong acousto-optical (AO) interaction is investigated. Expressions are obtained for the complex amplitudes of diffracted waves in the general case of an anisotropic medium. It is shown that with an increase in the dimensionless parameter of the Airy beam, the efficiency of Bragg diffraction decreases. At the same time, however, the shape of the modulation curve remains unchanged. It is established that the greatest efficiency of anisotropic Bragg diffraction is achieved for a case when the diff

Acousto-optic hybrid bistable devices have been studied previously. However, previous studies are limited only to the first-Bragg regime involving two diffracted orders. No actual comparison has been made between experimental results and theoretical predictions. A model including both acousto-optic diffraction and a nonlinear feedback path is studied in this thesis. Theoretical results based on diffraction involving two and four diffracted orders have been obtained and compared. Experimental results confirm the validity of the theoretical model.

They discuss the symmetry of modes to distinguish those that don't interfere in an efficient way.

A key advancement and the main focus of this chapter is the dynamic in situ control of quantum emitters using traveling sound waves generated by acoustic phonons in hexagonal boron nitride. As they travel through the material, these phonons interact with radiative defect states through deformation potential coupling, leading to tunable optical, electronic, and mechanical properties, thereby facilitating control over the spectral position and timing of single-photon emission. The spectral tuning is achieved within a bandwidth of approximately 2.5 meV, which is then combined with spectral detect
