Torque-operated gradient-index axicon
Yurij Vasylkiv, Mykola Smyk, Ihor Skab +1
We describe a gradient-index axicon based on twisting of crystals. We demonstrate that the focal length of the axicon can be efficiently operated by the torsion moment. The working…
Generation of double-charged optical vortices on the basis of electrooptic Kerr effect
Yurij Vasylkiv, Ihor Skab, Rostyslav Vlokh
We show that double-charged optical vortices can be generated with the help of Kerr electrooptic effect in either single crystals or isotropic media, including gaseous and liquid o…
Spin-to-orbital momentum conversion via electrooptic Pockels effect in crystals
Ihor Skab, Yurij Vasylkiv, Ihor Smaga +1
In the present work we have demonstrated a possibility for real-time operation by orbital an-gular momentum (OAM) of optical beams via Pockels effect in solid crystalline materials…
Optical anisotropy induced by torsion stresses in LiNbO3 crystals: appearance of an optical vortex
Ihor Skab, Yurij Vasylkiv, Viktoriya Savaryn +1
We report the results of studies of torsion effect on the optical birefringence in LiNbO3 crystals. We have found that twisting of those crystals causes a birefringence distributio…
Application of Small-Angular Magnetooptic Polarimetry for Study of Magnetogyration in (Ga0.3In0.7)2Se3 and SiO2 Crystals
O. Krupych, Yu. Vasylkiv, D. Adamenko +2
We present the results of studies for magnetogyration (MG) effect in (Ga0.3In0.7)2Se3 and SiO2 crystals performed with the small-angular polarimetric mapping technique. It is shown…
Conoscopic Patterns for Optically Uniaxial Gyrotropic Crystals in the Vicinity of Isotropic Point
Yu. Vasylkiv, Yu. Nastishin, R. Vlokh
We have presented computer simulations of conoscopic patterns occurring in optically uniaxial gyrotropic crystals in the vicinity of isotropic point for a number of sets of crystal…
