Summary
This study introduces a novel surface plasmon resonance (SPR) sensor using a dual-side polished microstructured optical fiber (MOF) for broad refractive index (RI) detection. The sensor achieves a wide RI range, surpassing traditional MOF-SPR sensors.
Area of Science:
- Optical Fiber Sensing
- Plasmonics
- Nanomaterials
Background:
- Microstructured optical fibers (MOFs) offer unique light-guiding properties for sensing applications.
- Surface plasmon resonance (SPR) is a sensitive technique for detecting changes in refractive index.
- Traditional MOF-SPR sensors often have limited analyte refractive index (RI) detection ranges.
