Technology
The invention is a new waveguide geometry that enhances the interaction between the agent and light and increases signal strength for on-chip detection.
Problem Addressed
Current attempts to detect chemical or biological agents on a single chip have difficulty integrating all elements to achieve a sensor with high signal-to-noise and a small footprint: sensors, waveguides, and photodetectors.
Advantages
- Small footprint and high sensitivity
- CMOS compatible fabrication
