Abstract

Based on a series of numerical results calculated by the transfer-matrix method, we find that the λ/4 rule for one-dimensional (ID) optical films is also valid for 2D and 3D photonic crystals (PCs) in designing a large high-reflectance region (HRR), if the ID counterpart approximation is used for them. A detailed process of the ID counterpart approximation is described. The results of the ID counterparts of real 2D and 3D PCs are in good agreement with the λ/4 rule. Therefore, the λ/4 rule can be extended to 2D and 3D structures for designing large HRRs.
