Abstract
We demonstrate the use of photonic crystal fiber (PCF) joined in between two single mode fibers (SMF) as a concentration sensor. To realize this, one micrometer length PCF of hexagonal lattice is sandwiched between two SMF having one micrometer length each. To maximize the coupling between SMF and PCF, the core diameters are made equal. Then the output from a given input through this structure is analyzed with respect to different concentrations in the air holes of PCF using Finite Difference Time Domain (FDTD) method. It is found that the variation of electric field intensity at the output is linear with respect to concentration of alcohol.

Summary
Sensors based on photonic crystal structure (PCS) are gaining interest during last decade. We propose a novel concentration sensor based on photonic crystal fiber (PCF). The sensors based on PCS have limitation in fixing For this purpose the PCS-2D is firmly placed between two glass slides [3,4,5], before the incident signal is allowed to pass through it. In this proposed mechanism, the PCS is replaced by PCF and is placed between two single mode fibers.
