Conventional lens technologies face great challenges in applications requiring large
apertures and small f‐numbers, while a liquid crystal (LC) lens based on geometric phase is …

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 …

Polarization holography in photocrosslinkable polymer liquid crystals films is described. By
adjusting the polarization modes of the interference light beams, both “pure” polarization …

The holographic grating recording process in thin films of amorphous azobenzene-
functionalized polymers has been widely reported in the literature. In spite of the many …

Upon S0–S1 excitation, the pyrazoline derivative molecule (Z)-2-(4-nitrophenyl)-3-(1-phenyl-
4, 5-dihydro-1 H-pyrazol-3-yl) acrylonitrile, abbreviated as PY-oCNNO2, can be transformed …

The authors report on a biopolymeric material made of deoxyribonucleic acid (DNA)
complexed with the cationic surfactant cetyltrimethyl-ammonium (CTMA) and doped with the …

Seven new azo disperse dyes based on N-benzyl–N-ethyl–aniline were synthesized and
characterized by UV–Vis, FT-IR and 1H NMR spectroscopic techniques. The UV–visible …

In this study, the dye-doped polymer dispersed liquid crystals (PDLC) gratings techniques
performed by the various research groups or being developed are briefly reviewed …

The combination of a microstereolithography process and a high‐load ceramic suspension
is used to produce complex three‐dimensional alumina microparts. The object (see Figure) …

The laser-assisted holographic grating recording process in films of azobenzene
functionalized polymers is usually studied by observation of the efficiency of light scattering …
