Progress in the use of liquid‐crystal polarization grating (LCPG) to modulate unpolarized
(and polarized) light with a grating period as small as 6.3 μm is reported. Similar to LCPGs …

The measurement of complete polarimetric parameters for a broad spectrum of wavelengths
is challenging because of the multi-dimensional nature of the data and the need to …

Liquid crystal polarization gratings exhibit high diffraction efficiency (~ 100%) in thin material
layers comparable to the radiation wavelength. We demonstrate that they can be combined …

The ability of optical axis gratings (OAGs) to fully transfer the energy of an unpolarized
incident light beam into the±1st diffraction orders is explored below for development of a …

We report our recent experimental results on a new polarization-independent, liquid crystal
(LC) spatial light modulator (SLM). Based on a periodic nematic director profile, the …

We present a theoretical model in the framework of elastic continuum theory to describe the
behaviour of a liquid crystalline host doped with ferroelectric nanoparticles acting as a liquid …

An apparatus and method for fabricating high quality one-or two-dimensional diffractive
waveplates and arrays that exhibit high diffraction efficiency and capable of inexpen sive …

We report a numerical analysis of the liquid crystal polarization grating (LCPG) as an electro-
optically controlled, polarization independent light modulator. The 2D finite-difference time …
