Structured Organic Non-Linear Optics

Recent research progress and current research activities in the area of organic nonlinear optics (NLO) are summarized, and major challenges are discussed in this chapter with a focus on molecular engineering of materials in nanoscale. A general introduction to the field of organic NLO and structured organic nonlinear optics materials is presented along with recent highlights of device applications of the materials that are redefining the scope of the organic NLO. We provide an overview of structured organic NLO field with particular emphasis on the specific advantages to be gained, and new challenges associated with the structured materials in nanoscale that enable novel optical device applications possible compared to more conventional organic NLO. Moreover, we attempt to show how a systematic study of the structured organic NLO can bring traditional sciences and nanoscience together, and provide a perspective of the structured organic NLO as a crucial foundation for further development of nanophotonics, a nanoscience and technology.
