Abstract :
We report here the design of Fano resonance broadband reflectors based on two-dimensional photonic crystals on silicon-on-insulator. The impact of vertical confinements and buffer configurations was investigated with a three-dimensional finite-difference time-domain technique. Spectral red- and blue-shifts were obtained by controlling the effective buffer layer indices, with very good agreement between experimental and simulation results.
