Abstract
The principle and application of evanescent-wave chemical sensor is presented. The used capillary waveguide structure ensures good interaction between evanescent field of guided mode and measurand. Quasi monomode state can be easily achieved, which ensures the monoexponential response corresponding to the Lambert-Beer law. Good correspondence between calculated dispersion characteristics and measured cut-off was observed. The sensitive polymeric layer was used to achieve the sensitivity to gaseous NH3.
