摘要：We study analytically using the Green function approach, the transmission through a onedimensionalphotonic crystal formed by a periodic stack of two different materials. Therefractive index of these materials are n₁ = 1.47 and n₂ = 1.87 and their thicknesses ared₁ = 0.4 and d₂ = 0.6. We insert in the one-dimensional photonic crystal, two defect layersof refractive index n₀₁ and n₀₂, and their thicknesses d₀₁and d₀₂.The numerical resultsshow the apparition of defects modes inside the gap caused by the introduction of defectlayers in the photonic structure. The position of the defects layers affect the transmissionpeaks; when defects layers are near in structure, the transmission peaks are distant in theband gap, and when defect layers are distant, the transmission peaks appear to beapproached.
