Six different contamination parameters in their aqueous solution are investigated using two-dimensional (2-D) photonic structure and infrared (IR) laser beam. A 2-D structure deals with photonic crystal (PhC)-based ring resonator, which can detect the amount of contamination present in water. The proposed detection technique exhibits a high Q-factor and excellent selectivity for the sensing of different impurities. The parameters of the design are optimized through finite difference time domain (FDTD) method for sensing the impurity level in the sample, based on its distinct refractive indices. The performance of the device has been evaluated and discussed briefly in the article. The device has explored the possibility of highly selective label-free sensing for lab-on-chip applications.
