Photonics and Nonlinear Optics with Molecular Materials and Polymers
Abstract
We used a multidisciplinary approach to understand the structure- property relationship with an aim towards developing novel second-order and third-order nonlinear materials with enhanced performance for photonics applications. We used a combination of theoretical modeling and experimental measurement of nonlinearities in a group of systematically derivatized structures to understand the structure-property relationship. This approach was extremely useful in designing new structures with enhanced nonlinearities. We have incorporated organic second-order chromophores in sol-gel processed SiO2 and TiO2 composites which have been successfully electrically poled to form stable aligned structures. In-situ poling studies while monitoring second harmonic generation and electro-optic modulation were used to study the poling dynamics. The microstructures of sol-gel processed composites were investigated. A combination of optical Kerr-gate, transient absorption and degenerate four- wave mixing was used along with appropriate theoretical development to understand the nature of resonant third-order optical nonlinearity.
