Planar optical waveguide design for UV-nanoimprinted microring resonator based biosensors

This paper presents the development and use of novel concise mode diagrams as a fast and useful tool for designing planar optical waveguides. By usage of these mode diagrams, the waveguide geometry and materials can be conveniently chosen. The mode diagrams calculated with the so called Matrix-EIM are particularly useful for the design of straight planar waveguides manufactured by nanoimprinting to choose suitable combinations of polymers, geometries and substrates. The results correspond well to a commercial FEM solver and can be obtained faster. Some examples for UV-nanoimprinted polymers on oxidized standard silicon wafers are shown.
