Abstract :
In this paper, the finite-difference frequency-domain (FD-FD) method is employed to analyze the guided-wave properties of two-dimensional photonic crystals. An efficient numerical scheme is presented to deal with inhomogeneous periodic structures. Photonic band structures within an irreducible Brillouin zone are investigated in order to find the photonic bandgap within which wave propagation is prohibited. The effects of the filling factor, the dielectric contrast, and lattice constants, on the band-gap width and location are discussed.
