A technique for recording a matrix of ring-shaped microstructures due to the postpolymerization of an already oriented layer of liquid crystal polymer under the influence of a focused intensive light radiation is developed. Using this technique, a microstructures matrix patterned element is realized. The reorientation process of the microstructure with the twist orientation in a homogeneously planar-oriented...
A technique is developed for recording the centrally-symmetric liquid crystal phase plates with the anisotropic orientation of molecules providing a smooth change of the optical axis in a thin film of liquid crystal polymer. The technique enables one to record the elements with the cylindrically-symmetric and planar-symmetric distributions. Such structures can be used to develop the optical elements...
The numerical finite difference time domain (FDTD) model of liquid crystal diffraction phase grating is developed and the possibility to use this grating for the spatial-time control of radiation in the mid IR wavelength range is shown.
