We demonstrate the use of a switchable circular-to-point converter (SCPC) device based on holographic polymer-dispersed liquid-crystal technology for application in lidar detection and optical telecommunication. A SCPC device converts the Fabry-Perot ring pattern into a single point or an array of points, while an external electrical field on the SCPC deactivates the conversion. Stacking differ...

We have studied the effect of an applied field on a system of particles interacting with a LebwohlLasher potential, enclosed in a polymer-dispersed liquid-crystal droplet with radial boundary conditions. We have used Monte Carlo simulations on a wide temperature range for systems of N = 304 and 5832 particles with positive susceptivity anisotropy, and we have calculated order parameters, the mo...

Magnetic hybrid liquid crystalline composites have been obtained either by thermal decomposition of a cobalt precursor in a solution containing a liquid crystal polymer or by dispersing preformed cobalt nanorods in a liquid crystal polymer matrix. The final materials are all mesomorphous and ferromagnetic. Their magnetic characteristics are compared as a function of the synthesis method.

Low concentrating photovoltaic (LCPV) system has been studied extensively, which showed excellent potential for the building integration application. However, such a suffers from higher operating temperatures due to concentrated light exposed into solar cell. In this work, two different methods have used regulate temperature of cell without interference any other external mechanism. Two concept...

The study of polymer dispersed liquid crystals (PDLC), formed of sub-micron or micron size liquid crystal droplets embedded in a polymer matrix is attracting increasing attention, both for their fundamental interest and for their applications in display technology [ l-6 1. PDLC possess an extremely large surface-to-volume ratio so that the aligning effect of surface boundary conditions, which h...

In this paper we demonstrate photonic band-edge laser emission from emulsion-based polymer dispersed liquid crystals. The lasing medium consists of dye-doped chiral nematic droplets dispersed within a polymer matrix that spontaneously align as the film dries. Such lasers can be easily formed on single substrates with no alignment layers. The system combines the self-organizing periodic structur...

The electro-optical properties of polymer dispersed liquid crystal films vary with contents and applied electric field, but the analysis film morphology cannot directly reflect mechanism properties. Therefore, prepared by blending material E7 photopolymer NOA65 was applied. Herein, dielectric polarization regulated their related under different fields are revealed. results show that in frequenc...
