Abstract

High concentrations of dye may be prepared in combination with thermoplastic polymers and used in optical polymers as monomeric and dimeric molecular solutions. The method of preparing high concentration levels allows the control over the aggregation of dye molecules that is required to maintain effective nonlinear operation. The present invention is applicable to many systems and is essential to the successful production of working optical limiting devices and other optically transparent polymeric devices, as well as other photonic applications, such as nonlinear optics.
