Nonlinear Optical Processes in Organic Media: Large Non-Resonant Third Order Electronic Responses in High Performance Liquid Crystal Polymer Structures,
Abstract
Organic and polymer structures exhibit unuaually large, ultrafast second and third order nonlinear optical properties in a large number of structures, phases, and states. Rapid advances in the field can be achieved through further development of stable, high performance polymer structures having outstanding secondary properities as demonstrated, for example, by high performance liquid crystal polymers. For two such polymer systems, PBI and PBT, third harmonic generation measurements show that they possess large nonresonant third order optical susceptibilities whose origin resides in ultrafast, lossless excitations of highly charge correlated -electron states.
