Article Synopsis
- The paper introduces a new multiplexed sensing technique using a special RF filter combined with a polarization maintaining fiber Solc-Sagnac loop to measure various environmental parameters simultaneously.
- The system operates as a spectrum slicer and can detect frequency shifts in the passbands of a multi-passband microwave photonic filter due to changes in environmental conditions.
- Experimental results demonstrate the system's effectiveness in temperature sensing, with two different sensor heads showing distinct sensitivities and stable linearity, indicating that increased sensor count and sensitivity can be achieved with higher-order configurations.
