摘要：
In this paper, a novel design of circular photonic crystal fiber (C-PCF) gas sensor is presented and analyzed by full vectorial finite element method. The suggested design has a spiral porous core region to achieve high sensitivity. The geometrical parameters of the proposed sensor are studied to achieve high sensor sensitivity. The introduced C-PCF offers high sensitivity of72.04% at the wavelength of 1.33 mu m. The reported sensor also offers a compact, accurate and useful tool for detecting harmful gases over a wide transmission band from wavelength of1 mu m to 1.8 mu m.
