DISORDERED ONE-DIMENSIONAL METALLIC-DIELECTRIC PHOTONIC CRYSTAL REFLECTOR

The reflected properties of one-dimensional frequency-dependent metallic-dielectric photonic crystals are investigated when disorders are introduced for the first time. It is demonstrated that disordered metallic-dielectric photonic crystal provides remarkably high reflection range compared with the corresponding period metallic-dielectric one when the degree of disorder is moderately chosen, and a wider stop band will be obtained with the increasing of periods. At last, the reflected properties influenced by incident angle for different polarizations are also calculated and discussed.
