摘要：

In this paper, the photonic crystal biosensor is investigated theoretically with, concomitantly, high quality factor, transmission and sensitivity. This biosensor is made out of two waveguide couplers and one L2 resonant cavity formed by removing two air holes. For biosensor analysis, the 2D finite difference time domain (FDTD) method and the plane-wave expansion (PWE) approach are applied. Four slots placed into the cavity and the three rows of functionalized holes nearby the resonant cavities are filled with DNA. For the optimized structure, the biosensor quality factor is found to be over 3.7468 x 10(6)and the sensitivity is of order 460 nm/RIU. The designed structure has high sensitivity, which is an important parameter in biosensing applications.
