Design and Analysis of Decagonal Photonic Crystal Fiber for Liquid Sensing
In this paper, the design of a microstructured decagonal Photonic Crystal Fiber (D-PCF) has been proposed for liquid sensing application. The proposed fiber has been analyzed using full vector Finite Element Method (FEM). The core of the decagonal fiber is filled with two different liquid analytes, ethanol, and water and variation of sensitivity and confinement loss are investigated over a wide range of wavelength. The proposed D-PCF structure gives sensitivity 30.2% for ethanol and 27.05% for water and confinement loss achieved is 2.89 × 10−6 dB/m for ethanol and 3.67 × 10−6 dB/m for water, measured at a 1.33 µm wavelength.
