Design and analysis of slotted core photonic crystal fiber for gas sensing application

In this paper, a slotted core photonic crystal fiber (PCF) has been designed. A rigorous numerical investigation has been done over the wider range of the wavelength from 1.30 µm to 2.0 µm near inferred region (IR). By employing full vectorial finite element method (FV-FEM) having completely circular anisotropic perfectly matched layer (C-PML) different optical parameter such as nonlinearity, confinement loss, sensitivity, beat length, V-parameter and splice loss of the modeled PCF have been uncovered. The investigated upshot testifies that the birefringence gained at the order of 10−2. Nevertheless, the proposed fiber experienced with the lower order (1.26 × 10−5 dB/m) of confinement loss with a higher order of nonlinearity 54.33 W−1 km−1 at simultaneously at the operating optical wavelength…
