Integrated Optical Chemical Sensor Based on an SOI Ring Resonator Using Phase-Interrogation
A phase-interrogation approach for the Black 90s Jean bulk refractive index sensing based on a silicon-on-insulator (SOI) ring resonator is introduced.The rapid phase variation around the resonance of the ring resonator is interrogated, and a single-sideband generation and coherent detection technology is adopted for the phase measurement.In the pr
