Development of Linear and Non-Linear Optical Materials Based on Sol-Gels Doped with Functional Materials
Abstract
Advanced optical and photonics applications require optical materials with improved functionality properties which meet the optical quality and thermal stability which is needed for these applications. Organic molecules/materials are exciting candidates for achieving required functionality properties. The common way to dope organic molecules has been to incorporate them in different host materials such as organic polymers. However, matrices based on organic materials are not suitable as opto-electronic devices due to limitations in optical quality and durability. In contrast, ceramic glassy materials are a favored choice for fabrication of opto-electronic devices. Ceramic materials have several intrinsic advantages over polymers, such as high temperature durability, chemical attack resistance, exceptional toughness and some ceramics possess excellent optical properties (e.g. SiO2, TiO2, Al2O3, and ZrO2). The drawback of ceramics as matrices for incorporation of organic chromophores is that classical ceramic fabrication methods use high temperature which is not suitable for organic molecules. A solution for this problem can be given by the Sol-gel technology [1-3] which allows fabricating of optical glassy matrices at low temperature and therefore allows doping of organic molecules in the inorganic based matrices. Such technology can open opportunities to develop advanced useful devices which can be used in a variety of optical and photonics applications.
