Abstract
Symmetry arguments play a central role in photonic crystals and govern the properties of the allowed modes both qualitatively and quantitatively. The inclusion of one much smaller rod inside the cavity without affecting rest of the lattice distorts the symmetry of the lattice drastically. This results in frequency splitting of otherwise degenerate modes, which has been correlated with the changes in energy density and packing fraction. We present strategies that allow complete control over the spatial distribution of the underlying modes using such small rods.
