In order to develop polymers with sufficiently large third-order nonlinear susceptibility (χ<sup>(3)</sup>) for optical switching applications, CMDITR will refine current models that relate χ<sup>(3)</sup>  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<sup>(3)</sup>.
