aTORCH - acTive Optical Resonator Chip Innovative concepts for next generation high sensitivity label-free bio-sensors

Abstract (Deutsch)

The goal of this project is the development of an active, label-free optical resonator (bio)sensor chip. The combination of state-of-the-art planar waveguide (PWG) with distributed feedback laser and Bragg reflector technologies will lead to a highly sensitive label-free (bio)sensor chip. Introducing Bragg reflectors in the waveguide will result in an optical resonator, increasing the quality factor (Q-factor) of the system and hence increasing the overall sensitivity. Doping the waveguide will create an active cavity and will further increase the Q-factor (in the order of two magnitudes). The massively enhanced field-strength will yield a substantial increase in limit of detection (by one or two magnitudes) compared to existing detection-technologies (labeled and label-free) and will enable OBL (main implementation partner) to satisfy huge markets as the only supplier of this technology. The further development of the reader platform will help DYN (additional implementation partner) to grow and give them a key competitive advantage.
