Dual-Channel Photonic Crystal Fiber Sensor Integrating Hyperbolic Mode Resonance and Lossy Mode Resonance for Simultaneous Measurement of RI and Temperature
Hyperbolic mode resonance (HMR) has emerged as a solution to conventional sensing limitations. HMR is introduced into a photonic crystal fiber (PCF) for sensing in this research. A dual-channel PCF sensor for both refractive index (RI) and temperature measurement is proposed. The device has two independent sensing chan...
