In this paper Fibonacci photonic crystal biosensors with graphene Nano-layers under the Kretschmann configuration have been investigated. Band structure, surface modes and reflection spectrum have been calculated by well-known transfer matrix method. Results show that the band structure and the dispersion of the surface modes are deeply affected by the geometry of the proposed structure. In addition, the spatial distribution of the dielectrics plays a basic role in the performance of sensors. The comparison between the maximum amount of phase sensitivity in proposed sensors show that structures with complex Fibonacci sequence are significantly able to detect small differences in the surface refractive index.

Keywords: Photonic crystal, bio-sensor, Surface modes, transfer matrix.
