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…
