    Photonic Crystal Based Bio-Sensor Detection in Nanophotonic Structure Using FEM Method
    (Université de M'sila, 2019) Mehdi Ghoumazi; Abdesselam Hocini
    Background & Objective: In this article, a nano-cell coupled 2D photonic crystal waveguide bio- detection platform is proposed for the detection of organic liquids such as water, ethanol, glycerol, benzene and bromine for different refractive indices (n). The detection characteristics are analyzed and obtained for the band diagram, before and after change of radius (r) as well as after the injection of liquids into the heart of the nanostructure cell at the resonant wavelength (λ res). Also, we extracted variations from the power flow norm (P) to the resonance and the transmission (T) for each material. This nanostructure for different (n) materials used, gives (P) at different levels to the resonance. This explains the importance of the refractive index parameter (n) which plays a crucial role in the detection of materials.
