Abstract: This investigation studies the optical Kerr constant (n2) of liquid crystals with cell substrates being treated with gold-nanoparticle-doped alignment films using the Z-scan technique. The results indicate that the doping of gold nanoparticles into polyvinyl-alcohol alignment films in a liquid crystal cell enhances the optical Kerr constant, n2, of the liquid crystals. This enhancement is caused by the thermal effect of the absorption of light due to the localized surface plasmon resonance of gold nanoparticles. The magnitude and the sign of n2 of a sample can be modulated by a combination of the applied external electric and optical fields. Furthermore, the variation of n2 of the sample with ambient temperature is studied. [ABSTRACT FROM AUTHOR]
