Abstract

Second-order nonlinear processes are electric-dipole-forbidden in centrosymmetric materials. For organic materials, noncentrosymmetry is relatively easy to achieve on the molecular level. However, for macroscopic noncentrosymmetry, such materials need to be poled. This results in a thermodynamically unstable material whose nonlinearity tends to relax with time. Isotropic materials are usually also neglected as second-order materials. However, isotropic chiral materials are noncentrosymmetric and possess a nonvanishing second-order response, as shown by sum-frequency generation.
