Overview

In order to develop polymers with sufficiently large third-order nonlinear susceptibility (χ(3)) for optical switching applications, CMDITR will refine current models that relate χ(3) to chemical structure. Specifically, CMDITR is developing materials with extensive delocalization beyond that which can be found in simple polymers, and with heightened optical nonlinearities arising from charge-transfer transitions. These approaches may yield materials with unprecedented performance at telecommunication wavelengths. In addition, CMDITR will investigate applications that take advantage of efficient twophoton absorption and third-harmonic generation. While ordering of chromophores is a well-understood key element in second-order nonlinear optical materials, the role of order in third-order nonlinear optical materials is poorly understood. Accordingly CMDITR will examine, both theoretically and experimentally, how chromophore ordering and aggregation can be used to significantly enhance χ(3).
