The sol-gel method is being investigated as a generalized strategy for fabricating planar waveguide chemical sensors and biosensors. Recently, a technically simple sol-gel dip-coating method has been developed to fabricate high quality glass integrated optical waveguides (TOWs) that support a single guided mode at visible wavelengths and that have propagation losses of less than 0.2 dB/cm. Subsequently, these waveguides have been used as a basis for development of a novel chemical sensing platform designed for optical detection analytes that form a light-absorbing complex within the evanescent field of the planar IOW in contact with a sample medium.
