Abstract: The effect of WS$_2$ nanotubes on the rotation of the polarization plane of $p$-type laser radiation in the nematic liquid-crystal composites based on 4'-pentyl-4-biphenylcarbonitrile (5CB) has been considered. The correlation between the concentration of the injected sensitizer and the phase shift of the optical beam has been demonstrated. The prospects of these materials in display technologies, laser technology and quantum cryptography has been shown.

Keywords: liquid crystals, sensitizing, WS$_2$ nanotubes, rotation of the light plane of polarization.
