Application of sol-gel-developed integrated optic devices to biochemical fiber optic sensors based on polarimetric interferometry

摘要

Principles of integrated optical sensors based on polarimetric interferometry are presented in the paper. A wide area of their applications in biochemistry includes monitoring of protein concentration in solutions, detection of antibodies as well as indirect investigation of chemical reactions, based on precise measurement of complex refractive index. In order to address a problem of irreversibility of wide group of biological processes and chemical reactions as well as to decrease cost of the sensors, authors propose to develop disposable measurement converters and to use optical components made from sol-gel derived hybrid polymers. The technology of hybrid materials synthesis and subsequent planar waveguides manufacturing as well as their properties are shown.
