Summary:The cholesterol detection of human blood using a two-dimensional photonic crystal biosensor has been studied in this paper. The structure calculations are done using Plane Wave Expansion (PWE) and Finite Difference Time Domain (FDTD). Photonic crystals can be used to detect biological components by utilizing a two-dimensional structure and resonator nano ring. These nano rings cause waveguide and resonator coupling. The cylinders around the sensing region have investigated the improvement structure output. The quality factor and figure of merit (FOM) for this sensor are 4988 and 57.14 RIU −1 , respectively, and the low detection limit (DL) is 0.001(RIU), with a sensitivity of 32 (nm/RIU).
