Abstract
The method of assigning irreducible representations to modes in three-dimensional photonic structures is applied to the two-dimensional triangular air-silica lattice with out-of-plane wave propagation. In particular prediction of spatial symmetries of the crystal modes is addressed. We show how the photonic bands are affected by different rod radii and out-of-plane components from a group-theoretical point of view.
One particular defect mode is analyzed and the structure which is optimal for air-guidance is found. $CPY 2004 Optical Society of America.
