A circular photonic crystal fiber (C-PCF) structure is presented in this paper as a chemical sensor where both core and cladding are micro structured. Finite element method (FEM) has been applied to investigate the propagation characteristics of proposed C-PCF structure. Relative sensitivity and Confinement loss are numerically examined and optimized by varying the different parameters of the proposed structure. Finally, it is found that the simple 3 rings C-PCF structure shows higher sensitivity as well as lower confinement loss at the wavelength 1.33μm.read more
