On quantifying the spin angular momentum density of light
Xiaoyu Zheng, Peter Palffy-Muhoray
In addition to energy, light carries linear and angular momentum. These are key quantities in rapidly developing optics research and in technologies focusing on light induced force…
Modeling the Mechanisms of the Photomechanical Response of a Nematic Liquid Crystal Elastomer
Nathan J. Dawson, Mark G. Kuzyk, Jeremy Neal +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 he…
Experimental Studies of the Mechanisms of Photomechanical Effects in a Nematic Liquid Crystal Elastomer in a Photomechanical Optical Device Geometry
Nathan J. Dawson, Mark G. Kuzyk, Jeremy Neal +2
Azo-dye-doped liquid crystal elastomers (LCEs) are known to show a strong photomechanical response. We report on experiments that suggest that photothermal heating is the underlyin…
Cascading of Liquid Crystal Elastomer Photomechanical Optical Devices
Nathan J. Dawson, Mark G. Kuzyk, Jeremy Neal +2
Photomechanical actuation is demonstrated in two coupled liquid crystal elastomer photomechanical optical devices (PODs) acting in series. The response function of an individual PO…
