Photonic Crystal Fiber–Based Surface Plasmon Resonance Sensor for Precise Biochemical Refractive Index Sensing

In this work, a D-shaped Photonic Crystal Fiber (PCF) sensor with a detection range of 1.30–1.35 is proposed, including Gold (Au), Titanium Dioxide (TiO₂), graphene, and a functionalized sensing region. Instead of filling or coating inside the PCF’s air holes, the Gold (Au) layer is appli...
