Paper Abstract

Nonlinear optical processes in ic-electron organic and polymer systems have attracted considerable study because their fundamental understanding has led to observations of new phenomena and new theoretical findings and to the development of new materials and devices of considerable promise1. The ic-electron excitations occurring on the individual molecular, or polymer chain, units are the basic origin of the observed large nonresonant nonlinear optical coefficients. The coefficients are broad band and ultrafast, and, as shown by theory and experiment, their sign, magnitude, and dispersion are determined by many-body electron correlation effects1. The field has now arrived at a critical crossroad to realize actual technological applications. Table 1 summarizes many of the key features of nonlinear optical polymers. Activities have increasingly centered on high performance materials that comply with device manufacturing and end-use conditions. The main attractions for applications remain the low cost, practical materials processing associated with polymer films, fibers, and bulk components. In an important recent development in data communications networks, a new application area may be emerging for optical polymer materials in the form of high band width polymer optical fibers (POF). In this review, we briefly summarize several recent developments in organic nonlinear optics. The summary is intended to illustrate the rich variety of developments in the field. The topics include exciton strings, photoactive proteins, polymer optical fibers for data communications, two photon states in third order optical processes, electrooptic polymers, photorefractive polymers, octopolar organometallic complexes, and multigigahertz electrooptic modulators.
