Electric-Field-Modulated Circular-Difference Effects in Second-Harmonic Generation from a Chiral Liquid Crystal

Abstract

Oriented by an electric field (but not otherwise), a lyotropic nematic phase of helical discotic 1 in dodecane exhibits second-harmonic generation, the intensity of which is affected by the helicity of the irradiating circularly polarized light. The change reverses sign when the polarity of the orienting electric field reverses.
