Ultra-High Sensitivity Terahertz Dual-Parameter Sensing Based on Eccentric-Core Photonic Crystal Fiber
To overcome the temperature cross‑sensitivity common in single‑parameter sensing, as well as the insufficient sensitivity and limited penetration depth of conventional near‑ and mid‑infrared sensors, this paper proposes an ultrahigh‑sensitivity THz dual‑parameter sensor based on an eccentric PCF. The proposed structure...
