In liquid crystal devices (LCDs) the indium tin oxide (ITO) films are traditionally used as transparent and conductive electrodes. However, today, due to the development of multichannel optical communication, the need for flexible LCDs and multilayer

In order to achieve low light loss and a high extinction ratio in a vector vortex waveplate (VVW) based coronagraph, a precise half wave retardation at the operational wavelengths is necessary. The inversely twisted liquid crystal polymer (LCP) layer

We show the opportunity to fabricate a device for measuring circular dichroism (CD) in real time, the key element of which is a liquid crystal cycloidal diffractive waveplate (CDW). We present the results of simulations carried out to estimate the ac

We report on the realization of a light beam splitting effect based on a light sensitive diffractive structure. The periodic structure is realized in soft composite materials doped with an high performance light sensitive Liquid Crystal. The capabili

Small singularity size is critical for achieving low light loss and high contrast for vector vortex waveplate (VVW) based coronagraph. In the opto-mechanical system for recording VVW with photoalignment, reshaping the center light intensity distribut

The dynamics of the direct volume expansion mechanism of light induced hydrodynamic motions in homeotropic and hybrid oriented NLC have been studied theoretically. In case of homeotropic initial orientation of NLC molecules the velocity gradient indu

The Vector Vortex Coronagraph (VVC) is one of the most attractive new-generation coronagraphs for ground- and space-based exoplanet imaging/characterization instruments, as recently demonstrated on sky at Palomar and in the laboratory at JPL, and Hok
