Realization of Potassium Chloride Sensor Using 2D Photonic Crystal Structure
Abstract: In the present study, the concentration of potassium chloride in their aqueous solution is investigated using optical sensor. Optical sensor is realized by 2D photonic crystal structure (PCS), which is made up of silicon materials (background/substrate) consisting of 8×8 air holes containing aqueous potassium chloride solution. The principle of measurement is based on logarithmic variation of photonic band gap (PBG) with respect to different concentrations of potassium chloride. The PBG …
