Summary
This study introduces a silicon photonic polarization multiplexing sensor for precise measurements. It achieves a wide measurement range and high resolution simultaneously for temperature and refractive index sensing.
Area of Science:
- Photonics and optical sensing technologies.
- Integrated photonics for advanced sensor design.
Background:
- Traditional sensors often face trade-offs between measurement range and resolution.
- Silicon photonics offers a platform for miniaturized and high-performance optical devices.
Discussion:
- A novel silicon photonic sensor utilizes polarization multiplexing (PM) with a Fabry-Pérot (FP) resonator and a microring resonator (MRR).
- The FP resonator operates on the transverse-electric (TE) mode for a large range, while the MRR operates on the transverse-magnetic (TM) mode for high resolution.
- This dual-mode operation overcomes the typical range-resolution limitations in a single sensor.
Key Insights:
- Demonstrated temperature sensing with a 113 °C range and 0.06 °C resolution.
- Achieved refractive index sensing with a 0.58 RIU range and 0.002 RIU resolution.
- Simultaneous large range and high resolution achieved through polarization multiplexing.
Outlook:
- Potential for miniaturized, high-performance sensors in various applications.
- Further integration of PM sensors for complex environmental and biological monitoring.
- Advancements in silicon photonic resonator design for enhanced sensing capabilities.
