Title: Characterization of bipolar and radial nematic liquid crystal droplets using laser-tweezers
Author(s): Murazawa, Naoki; Juodkazis, Saulius; Misawa, Hiroaki
Abstract: Bipolar and radial droplets of 4-pentyl-4'-cyanobiphenyl were manipulated using circularly polarized laser-tweezers. Light-induced birefringence arising from orientational nonlinearity was observed and measured for the radial droplets. The highest laser trapping power used 0.5 W induced a birefringence of 0.02 and hence the spinning of the droplets was observed.
