Power Analysis of Photonic Sensor for Detection of E-coli in Water

摘要

The optical photonic crystal sensor design is proposed, which contains Silicon (Si) circular rods, made in a square lattice structure. The input point has a light source of wavelength 1.55um and has two output points to observe the output. The paper proposed different Photonic Crystal structure and power analysis for the same. The calculation for change in Refractive index value and power - wavelength shift for Water(1.33 RI) and E-coli (1.388 RI bacteria in water) analyte is analyzed and plotted. The procedure repeated for proposed different structures. Using a new design of 2D slab, we have observed the power output, amplitude and quality factor for different structure. The quality factor for proposed structure is observed and Cantilever structure is giving very high quality factor of 25954.
