Theory of optical bistability in the region of exciton resonances

Correlation optics within the framework of the correlation optics conference at the base of Chernivtsi National University

“…Figure 1. The paper titled "Ukraine and Singular Optics" in the high-impact scientific journal "NanoPhotonics" 4 Back in 1980, the Department of Correlation Optics was created at Chernivtsi State University, making it the first in the world. Exactly there, the idea of metrological evaluation (quantitative measurement) of the degree of statistical correlation of structurally inhomogeneous fields was practically implemented.…”

“…The indicator of growing popularity of the discussed topic and the contribution to this growth is the fact that the scientific journal "Photonics" published by Jade University plans to dedicate one of its upcoming special issues to "Correlation Optics" (https://www.mdpi.com/journal/photonics/special_issues/151L6A0DAE). This special issue will cover a range of topics closely related to our research focus [1][2][3][4][12][13][14][15][16][17][18] , which is presented in 15 proceedings (SPIE Proceedings), three special issues of the journal "Applied Optics", special issue of scientific journal Advanced in Optical Technologies named "Correlation Optics" and four scientific collective monographs based on the results of the "Correlation Optics" scientific conference since 1991.…”

<title>Magneto-optical bistability of Frenkel excitons</title>

“…The value S(&) is called the form function of the exciton absorption band and D is the matrix element of the interaction of light with the crystal; its value depends on the angle (q) between the polarization wave and the dipole moment ofthe crystal transition into given da exciton state Da D0(ë0 aa) Doa ccs q (2) Hence it follows that the interaction of light and the ciystal is maximum. when the photon polarization vector is parallel to the given dipole moment of the quantum transition ( = 0).…”

Using the Hilbert transform for the investigation of structurally heterogeneous packaging materials

“…In this work, the use of carbon nanoparticles and the Hilbert transformation is proposed to restore the phase information contained in the optical speckle field registered from the surface of a glossy material [12][13][14][15][16][17] . Carbon nanoparticles are characterized by a size in the range of 65-85 nm with a strong absorption [18][19][20] at a wavelength of 405 nm, a luminescence maximum of which is at a wavelength of 530 nm and a weak absorption at a wavelength of He-Ne laser (633 nm).…”
