The Local Field Factor and Microscopic Cascading: A Self-Consistent Method Applied to Confined Systems of Molecules
Nathan J. Dawson, James H. Andrews
We use a simplified self-consistent method to address nonlinear-optical cascading phenomena, which shows added microscopic cascading contributions in high-ordered nonlinear suscept…
Testing the diffusion hypothesis as a mechanism of self-healing in Disperse orange 11 doped in PMMA
Shiva K. Ramini, Nathan Dawson, Mark G. Kuzyk
In this work, we show that reversible photodegradation of Disperse Orange 11 doped in PMMA is not due to dye diffusion - a common phenomenon observed in many dye-doped polymers. Th…
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…
A quantum mechanical model of the upper bounds of the cascading contribution to the second hyperpolarizability
Nathan J. Dawson, Benjamin R. Anderson, Jennifer L. Schei +1
Microscopic cascading of second-order nonlinearities between two molecules has been proposed to yield an enhanced third-order molecular nonlinear-optical response. In this contribu…
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…
A classical model of the upper bounds of the cascading contribution to the second hyperpolarizability
Nathan J. Dawson, Benjamin R. Anderson, Jennifer L. Schei +1
We investigate whether microscopic cascading of second-order nonlinearities of two molecules in the side-by-side configuration can lead to a third-order molecular nonlinear-optical…
