Grating Couplers for Chip-Integrated Optofluidic Fluorescence Quantification

Fluorescence-based assays are widespread in life sciences and used for instance in diagnostics, cell sorting, or to resolve cellular and tissue structures. Optofluidic engineering can help improve such assays, especially when sensitivity or throughput are important. Towards optofluidic integration, we combine a silicon nitride photonic chip including grating couplers for exciting and detecting flu...
