Poled nematic films, where the asymmetric axis responsible for second harmonic generation (SHG) is not in the poling direction are reported. Liquid crystalline polymers containing dopant chromophores, or side chain groups with high molecular hyperpolarizabilies exhibit this effect which has potential applications in nonlinear optics.
