Abstract :
We demonstrate a cost-effective silicon microring-based bio/chemical sensor, which integrates vertical grating couplers, two cascaded microrings for optical sensing and electrical tracing, and Ge photodetector for direct sensing interrogation. Detection limit of 1.5×10-5 is demonstrated.
