Abstract
Using optical second-harmonic generation, we measure the anisotropic orientation behavior of liquid-crystal siloxane molecules embedded in a ferroelectric liquid-crystal matrix. An exceedingly high degree of in-plane anisotropy is observed, which could be unambiguously attributed to effective second-order susceptibility components , , and . All coordinates refer to a rectangular surface-stabilized ferroelectric liquid-crystal sample cell with z the surface normal and y the direction of the unidirectionally rubbed interior polyimide layer. The second-harmonic efficiency that is due to the dominant electric-field-induced component of this binary guest–host system exceeds the efficiency of other liquid-crystal systems reported so far by more than one order of magnitude.
