The ultra-compact biosensor based on the two-dimensional (2D) photonic crystal (PhC) microcavity is investigated. The performances of the sensor are analyzed theoretically using the Fabry-Perot (F-P) cavity model and simulated using the finite-difference time-domain (FDTD) method. The simulation results go along with the theoretical analysis.
