Abstract : The development of organic inorganic second order nonlinear optical materials is discussed in light of the need to obtain practical (high performance, stable operation, processable and low cost) alternatives to inorganic crystals. Sol gel materials have well established optical properties attributed to their superior purity and homogeneity. Processing methods of sol gel materials permit the inclusion of numerous dopants to achieve final materials having variable and desirable properties. These materials have low optical losses and physical properties which are amenable to integrated optical devices. A number of chromophores and ormosil materials have been designed, synthesized, processed, and tested. Several composite materials are described which have high optical nonlinearities and low optical losses when they are prepared as optical waveguides. Many of these films demonstrate stable performance at room temperature and can be considered for selected applications. Specific recommendations for continued work in improving thermal stability are suggested.
