## Figure 3.
Photonic band structures corresponding to a square lattice of cylindrical air holes
in a Si matrix. The ratios r/a and h/a were set as 0.38 and 0.4, respectively; the parameters correspond to a fluence of
5 × 10^{10}/cm and a current density of 300 mA/cm^{2}, ϵ = 11.56 being the dielectric constant of Si. (a) Slabs bands with even symmetry with respect to the z-plane (TE-like). (b) Slabs bands with odd symmetry with respect to the z-plane (TM-like).
