Abstract

Optical rotation has been induced in thin samples of cholesteric liquid crystals by the application of dc or 60-Hz ac electric fields in the direction of light propagation. A power law dependence of the form R = KE^xwas found where R is the change in net rotation, E is the rms electric field strength, K is a constant, and x equals approximately 2.3.
