摘要：

A novel design of circular photonic crystal fiber (C-PCF) gas sensor is presented and analyzed by full vectorial finite element method. The suggested structure has a spiral porous Core region to achieve high light interaction with the applied gas. The geometrical parameters of the proposed sensor are studied to achieve high sensor sensitivity. The introduced C-PCF offers high relative sensitivity of 72.04% at a wavelength of 1.33 mu m. The reported gas sensor also offers a compact, accurate and useful tool for detecting harmful gases over a wide transmission band from wavelength of 1 mu m to 1.8 mu m.
