Highly Sensitive Twin Resonance Coupling Refractive Index Sensor Based on Gold- and MgF<sub>2</sub>-Coated Nano Metal Films

Highly Sensitive Twin Resonance Coupling Refractive Index Sensor Based on Gold- and MgF<sub>2</sub>-Coated Nano Metal Films

A plasmonic material-coated circular-shaped photonic crystal fiber (C-PCF) sensor based on surface plasmon resonance (SPR) is proposed to explore the optical guiding performance of the refractive index (RI) sensing at 1.7–3.7 <inline-formula>μ</inline-formula>m. A twin resonance coupling...
