Numerical Study of the Fabrication Tolerance in Photonic Crystal Devices — •Javad Zarbakhsh, Farnaz Ghods Isfahani, and Kurt Hingerl — Christian Doppler Labor fuer Oberflaechenoptische Methoden, Institut fuer Halbleiter und Festkoerperphysik, Universitaet Linz, A-4040 Linz, Austria

We studied the fabrication tolerance and design flexibility of conventional Photonic Crystals(PC) structures. In fact, theoretically how flexible the PCs could be regarding to change of periodicity and the size of the elements to retain the favorable band gap width. Adhering to some constraints the changes in the photonic band gap width is negligible and the confine modes do not penetrate the PCs. The results of Finite Difference Time Domain (FDTD) are in agreement with the results of plain wave expansion (PWE). This brings another degrees of freedom for designing of the photonic crystal nanodevices.
