Abstract
In this paper, we have proposed a novel concentration sensor using circular lattice photonic crystal fiber (PCF) sandwiched
in between two single mode fibers (SMF). For simulating this, 1 µm length PCF of circular lattice is placed between two
SMF having length 1 µm length each. To provide better coupling between SMF and PCF, the diameters of the core are
made equal. The input is fed at one end and the output is analysed at another end with respect to different concentrations
of alcohol in the air holes of PCF using Finite Difference Time Domain (FDTD) method. The output at the end of the sensor
shows that the variation of electric field intensity is linear with respect to concentration of alcohol..
