چکیده انگلیسی
In this paper, porous shaped photonic crystal fiber (P-PCF) has been proposed for chemical sensing purposes where both core and cladding air holes are rearranged in porous manner. Different guiding properties of proposed P-PCF has been numerically evaluated by utilizing well-known finite element method (FEM). The relative sensitivity, confinement loss, effective area, beam divergence and marquise spot size are investigated by tuning distinct geometrical parameters like air holes diameter and pitch in the core as well as cladding region over a wider range (0.6 μm-2.0 μm) of wavelength. The proposed P-PCF is retained with two rings air hole in a core and five rings air hole in the cladding which maximizes the investigated guiding properties expressively compare to the prior-PCF structures. After finishing the investigation process, it is nicely also exhibited that the relative sensitivity is increasable with the increment of the wavelength through the communication band O + E + S + C + L + U. Higher band shows higher sensitivity for all applied liquids. Optimized P-PCF has high impact in the area of the chemical as well as gas sensing purposes.
