Optical Sensing Properties Optimization of a Slot-Waveguide-Based Silicon Ring Resonator Biosensor

摘要：

　　An optical biosensor with a slot-waveguide-based micro-ring resonator on silicon-on-insulator (SOI) is reported.By numerical analyzing,a small-sized sensor of 25× 15μm2 with a sensitivity of 594nm/RIU can be achieved for NaCl solution,which is about eight times of that of the conventional micro-ring sensor.The free spectral range of 25.6nm and a quality factor Q of 430 are also observed.If SNR is more important,an asymmetric coefficient of 0.7 can be introduced to enhance Q factor.Our analysis also shows that the sensor has good sensing characteristics to other organic solutions.
