A compact and robust mid-infrared refractive index-based microstructured fiber sensor with high sensitivity is developed for monitoring analytes in liquids and gases. Resonant core-shell elements f…
A novel terahertz (THz) photonic crystal fiber (PCF) that yields single-polarization single-mode (SPSM) propagation over an ultra-wide bandwidth is designed and analyzed. The PCF is based upon a tr…
