Self-assembling of liquid-crystal metasurfaces on polymer layers patterned by a focused ion beam manifests itself in distinctly colored optical transmission, as light from certain spectral bands is efficiently diffracted by the periodic liquid crysta

We study electrically driven switching of liquid-crystal-metasurfaces between diffracting and transmitting states. We fabricate periodic metasurfaces that self-assemble upon stripe patterns and scatter light symmetrically into several diffraction ord

Micro-scale patterning of alignment layers with focused ion beam produces liquid-crystal-metasurfaces with strong diffraction. We study the electro-optical switching from diffraction to transmission mode and show that it occurs within milliseconds.

Liquid-crystal-metasurfaces self-assemble on polymer films prepared by periodic and superperiodic FIB patterning. Optimizing their design we achieve precise control of the transmitted light phase and direction tunable by low-voltage electric pulses.

The ongoing interest in fast liquid crystal (LC) modes stimulated by display technology and new applications has motivated us to study in detail the in-plane switching (IPS) vertically aligned (VA) mode. We have studied how the decrease of the period

We have studied the alignment of a nematic liquid crystal (LC) material on aluminum subwavelength nanogratings as a function of the period, p, and the slit width to period ratio, w/p. A method, based on Fourier analysis of the transmittance spectra o

We report the formation of high optical power microlenses in the near-surface region of the liquid crystal layer. Such microlenses, possessing a very small focal length f at a rather large aperture A ( f / A ∼ 2 ), are able to focus the light into
