Abstract:

It is studied the omnidirectional reflection properties of one-dimensional photonic crystals by using the bandgap theory deduced by the transfer matrix method. Investigations show that the construct parameters affect significantly the omnidirectional reflectivity band of a photonic crystal. In order to extensive the omnidirectional reflectivity band, some methods are proposed to increase the refractive index of dielectrics, the ratio of the high and low refractive index, and make the ratio of the optical thickness near to 0.85. The conclusion is helpful for designing a dielectric omnidirectional reflector.
