Comparison of the Sensitivity of a Polymer Waveguide in the Classical and Reverse Symmetry System

In this paper an analysis of two types of planar waveguides (with the conventional type of the layer and the reverse symmetry waveguide) is presented. In both types of the structure the polymer SU8 was used. In respect of its properties, this polymer is suitable as a waveguide layer. The analysis presented in this paper describes those structures working as sensors. We made a comparison of both types of configuration. We made a detailed analysis of the sensitivity of the covering layer when the thickness of the waveguide layer is changing and when the length of the wave activating the structure is changing, too.
