Fabrication and characterization of photonic crystal structures for gas sensor applications

The guiding of infrared radiation via waveguides is of great interest for a wide range of applications, such as absorption sensing in the infrared spectral range. Highly integrated gas sensors use the evanescent field of the guided radiation in order to measure for example the CO2 concentration in ambient atmosphere. However, the miniaturization of such sensors without reducing the resolution is challenging.
To address this problem this talk introduces a hybrid system of photonic crystals and surface plasmon polaritons as a waveguide. The focus of the talk will be on the fabrication of the waveguides and the characterization of plasmonic materials.
