Second Order Nonlinear Optics in Ionically Self-Assembled Thin Films
… the noncentrosymmetric structure required for second order nonlinear optical responses. Second harmonic generation is used as a probe of the second-order nonlinear optical susceptibility (c(2)) of ionic self-assembled monolayer (ISAM) films. Films produced from the ISAM technique are shown to …

Organic Self-Assembled Thin Films for Second Order Nonlinear Optics
… numerous methods have been developed to produce nonlinear optically (NLO)-active polymeric films for such purposes. Ionic self-assembled multilayer (ISAM) films are a recently developed class of materials that allows detailed structural and thickness control at the molecular level, combined with …

Organic materials for second-order nonlinear optics: Approaches to optimizing and stabilizing nonlinear optical effects
… research has been to establish the potential of nonlinear optics (NLO) to study relationships between chemical structure and properties of organic materials. Using properly constructed molecules or photoactive dopants, phenomena such as molecular relaxation, dipolar ordering, poling dynamics, and …
