New Generation Photonics Materials: Design, Development, Characterization and Applications

Abstract

A significant amount of research was accomplished in the design, development, characterization and applications of two types of photonic materials: Multiphoton absorbing materials and hybrid nanocomposites for photorefractivity. We synthesized a new class of two-photon dyes which are pyridinum-based inner salts (covalently bonded) and achieved two- photon lasing. Another accomplishment was to produce two-photon active liquid dyes with enhanced number density. In collaboration with AFRL at Dayton who synthesized 1,3,5 triazine-based octupolar molecules, we characterized their two-photon properties using our newly developed femtosecond white light continuum transient absorption method. This method was also utilized to characterize the two-photon absorption spectrum of a series of highly two-photon active chromophores synthesized by the AFRL at Dayton. We also successfully synthesized a number of highly efficient three-photon materials.
