Finite Element Modeling Methods for Photonics (Artech House Applied Photonics)

Inside the green rectangle: Comparison between the E z field patterns at the M point calculated with MPB on the left and FEM on the right for the first eight bands the band index increases from bottom to top. The band gap region is clearly distinguishable and a weakly localized defect mode merging from the upper band can be seen. An hexagonal supercell has been used for the FEM calculation. The rod radii has been set to 0.

The defect mode clearly shows up in the gap region, since the defect state is strongly confined. All these patterns match the ones presented in Fig. The band gap increases and so it does the defect mode localization around the point defect. The insets show a detailed view of the defect mode curves indicated by the red arrow. Logarithmic scale has been used for the vertical axis. The radii of the rods are a 0. Logarithmic scale has been used for both axes.

A point source is excited in the cavity but after some periods the source is extinguished and although the electromagnetic field still remains in the cavity it experiences an exponential decay.
