    dct:description """
              Dense wavelength division multiplexing (D.W.D.M.) significantly increases the optical telecommunication<br />transmission rates. To separate the channels, narrow band spectral filters are necessary.<br />Resonant gratings, composed with a grating engraved on a planar waveguide, are a<br />potential solution. These structures support eigenmodes, which can be excited by a wave coming<br />out of an optical fiber. The excitation creates a resonance peak in the reflected beam,<br />for a given wavelength and incidence angle. In general, the peak does not exhibit the qualities<br />required for the D.W.D.M.: at oblique incidence, the angular and spectral tolerances are weak,<br />and the line shapes are polarization dependent. Combining photonic crystals concepts, a rigorous<br />phenomenological theory, and a perturbative theory, we design a filter that meet all the<br />conditions imposed by the D.W.D.M..<br />Key words: D.W.D.M., filters, resonance, grating,
