Paper Abstract

We present a novel waveguide sensor platform, combining monolithically integrated sensor waveguides with thin-film organic photodiodes on a single substrate. Aiming at the parallel detection of multiple parameters in a single sensor chip different sensing principles can be applied on the same basic sensor platform. Utilizing absorbance as sensing principle is demonstrated by an integrated carbon dioxide sensor, fluorescence as sensing principle is demonstrated by an integrated oxygen sensor. The versatility of this integrated waveguide platform is further demonstrated by employing surface plasmon resonance as sensing principle, enabling real-time and label-free detection of a wide range of analytes.
