The work presented in this thesis concerns the study and the simulation of a biosensor based on a two-dimensional photonic crystal to detect the chikungunya virus. The simulation results have designed and analyzed by using the finite difference time domain (FDTD) method under the OptiFDTD software, the band gap calculation is performed using the plane wave expansion method (PWE) under PWE solver, and MATLAB for plotting curves. The obtained results thanks to the design that we used, are very satisfactory because they show a very high sensitivity reaching 973.24um/RIU and transmission up to 69.2%, which makes it a very good support for the realization of our biosensor.
