Basic structures of integrated photonic circuits for smart biosensor applications

Integrated optics concerns mainly the generation, guiding, and detection of light. Especially biosensing needs systems that incorporate electrical, electronic, and photonic devices for the detection of harmful substances, like synthetic oestrogens or plasticizers. We present here recent developments in the integration of our Si-based light emitter into a photonic circuit for a planar optical waveguide-based biodetection system.
