Abstract: In this paper, we have investigated Photonic Band Gap (PBG) of two dimensional Photonic Crystals (PhCs) for TE polarization. Effect of shape, size and orientation of scatteres on PBG in triangular lattice has been investigated. OptiFDTD software has been used to calculate PBG, having simulator, Planewave Band solver, based on plane wave expansion method. The scatterers are air holes in dielectric media. It has been found that PBG can be controlled by changing the scatterer's properties. A triangular lattice with hexagonal air holes is able to show maximum band gap in 2-D PhC. PBG for TE polarization has been calculated for air holes in triangular lattice with background dielectric material, Si and GaAs. It has been found that although the gap mid gap ratio is different in above two materials but band gap behavior is almost similar. © 2013 IEEE.
