Optical properties of a stack of layers of a cholesteric liquid crystal and an isotropic medium

Coupling of Defect Modes in Cholesteric Liquid Crystals Separated by Isotropic Polymeric Layers

“…Subsequently, they realized a quasi-periodic system using single-pitch CLCs and isotropic films of polyvinyl alcohol and fabricated a red-green-blue reflector [15]. There were further theoretical studies that considered reflectors [16,17,18], studied optical properties of composites of CLCs and isotropic layers [19,20,21,22] or calculated the DOS of a stack structure of CLCs and isotropic medium [23,24]. However, up until now, very little attention has been paid to the coupling of defect modes in such composite assemblies.…”

Photonic density of states of a stack of cholesteric liquid crystals and isotropic medium layers

“…They find a wide range of applications, in particular, in display manufacturing. The formation of multiple PBSs in one-dimensional multilayer structures containing CLC and isotropic layers has been reported in theoretical and experimental studies [4][5][6][7][8][9] . Analogous studies of one-dimensional multilayer structures including CLC and anisotropic layers were reported in 10 .…”

“…Here, we report the studies of optical, polarization, and lasing properties of a multilayer system consisting of CLC and isotropic medium layers ( Fig. 1) that were not considered in [4][5][6][7][8][9] . We discovered many new interesting properties of this system, which can find important applications.…”
