Abstract
Optical second-harmonic generation has been used to study the anisotro pic orientation behavior of liquid-crystal siloxane molecules embedded in a nematic and/or ferroelectric host matrix. All of the studied gue st-host systems show an exceedingly high degree of in-plane anisotropy along the direction of the rubbed interior polyimide layer of the sur face-stabilized liquid-crystal sample cell. A longitudinally applied e lectrical field leads to susceptibility components exceeding 1 pm/V fo r a poled sample cell of 5 mu m thickness containing 10% by weight of the siloxane guest in a nematic matrix.
