A pathway for a coherent topological transition from the splay to bend director configuration in liquid crystal layers has been previously described via order reconstruction in a two‐dimensional sheet in the plane of the liquid crystal layer. In th

In this paper, we explain the design principle of a reflective liquid crystal device using Poincare sphere analysis. The evolution of the polarization state of light progressing through the liquid crystal layer and a compensator is shown. The analysi

A polymer-wall-confined switchable diffractive liquid crystal light valve is investigated by two-dimensional finite-difference time-domain (FDTD) optical simulation and liquid crystal director field calculation for the first time. Under optimized con

The multidimensional alignment (MDA) technique realized by the polymer wall has been previously proposed as a means to stabilize the liquid crystal configurations for twist angles of 0 and 2π so that very low power and real bistable twisted nematic

There are numerous reports in the literature dealing with the electro-optical properties of PDLC with experiments designed to reduce the material's hysteresis. Most suggest strong interaction relationship between the liquid crystals and the polymeric

A bulk transition from the splay to bend state resulting from the application of a high voltage to a layer of liquid crystalline material has been previously observed experimentally, and has been explained as a reconstruction of the order in a two di

In this paper, we propose a new reflective LC phase modulator design by combining the advantage of the polymer wall to reduce the fringe field and an incorporated QWP to make the device polarization independent. This new design has promising applicat

LCoS imager performance depends on the liquid crystal (LC) operation mode that is being selected. In this paper we explain the design principle in an alternative way by using Poincare sphere analysis. The selection of the compensator parameters for t

— A single-crystal-silicon light-valve technology was created by optimizing a 0.8-mgr;m EEPROM process flow to satisfy the electrical and optical requirements of the light valve's transducer, a polymer-dispersed liquid crystal (PDLC).
