A phase-interrogation approach for the 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 proposed approach. https://www.itsmajorlook.com/top-deal-Dallas-Cowboys-logo-Fan-Decals-3-75-x-5-p32366-top-mega/
