Modeling the Mechanisms of the Photomechanical Response of a Nematic Liquid Crystal Elastomer
Modeling Nematic Liquid Crystal Elastomer
2011/9/2
Recent studies of azo-dye doped liquid crystal elastomers show a strong photomechanical response.We report on models that predict experimental results that suggest photothermal heating is the dominant...
Depth Profile of Optically Recorded Patterns in Light-Sensitive Liquid Crystal Elastomers
Depth Profile Optically Recorded Patterns Light-Sensitive Liquid Crystal Elastomers
2011/8/11
Abstract: We investigated nonlinear absorption and photobleaching processes in a liquid crystal elastomer (LCE) doped with light-sensitive azobenzene moiety. A conventional one-dimensional holographic...
Ultrathin optical switch based on a liquid crystal/silver nanoparticles mixture as a tunable indefinite medium
Ultrathin optical switch liquid crystal silver nanoparticles tunable indefinite medium
2011/8/2
Abstract: We predict that a liquid crystal/silver nanoparticles mixture can be designed so that, in a frequency range, its effective ordinary and extraordinary permittivities have real parts of differ...
Experimental Evidence of an Optical Shutter in Cholesteric Phase of a Double Hydrogen Bonded Liquid Crystal
Hydrogen bonded liquid crystal LTA+11BA Optical shutter Light modulator
2010/7/8
A novel series of double hydrogen bonded liquid crystals have been isolated. Hydrogen bond was formed between non mesogen chiral ingredient levo tartaric acid (LTA) and mesogenic undecyloxy benzoic ac...
Incoherent interaction of nematicons in bias-free liquid-crystal cells
Nonlinear optics liquid crystals nematicons
2010/4/8
We study experimentally the propagation dynamics and interaction of a pair of mutually incoherent nematicons: spatial optical solitons in nematic liquid crystals. In contrast to earlier studies, we co...
