Organic materials for second-order nonlinear optics: Approaches to optimizing and stabilizing nonlinear optical effects

The main objective of this 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 intermolecular forces in organic materials were investigated. A second objective has been to identify mechanisms to optimize and stabilize second harmonic generation (SHG) signals through materials processing techniques. This investigation includes studies in three main topics: nonlinear optical properties of magnetically aligned alloys of nematic polymers and organic dyes, two-dimensional polymers, and novel single crystal films that exhibit zero-field SHG.
