Applications of molecular dynamics simulation in nonlinear optics

Organic nonlinear optical molecular materials have a number of important applications in frequency transformation, electrooptic modulation, two-photon absorption and so on. In this paper, we introduce the main applications of molecular dynamics simulation in theoretical study on nonlinear optical properties of organic molecules, including the electric field poling effects, the local field factors, the nonlinear susceptibilities, and the two-photon absorption. In addition, the important roles played by molecular dynamics simulation in the study of solvent and aggregation effects are also illustrated in combination with the recent research.
