Abstract

We designed a gradual period one dimensional photonic crystals structure. The transmission spectra of this structure have been studied. The numerical result shows that the photonic band gap (PBG) width is enlarged and the photonic band gap shifts to longer wavelength in the case of normal incident. Verifying the incident angle, we obtained broadened total omnidirectional PBG of this gradual structure. The omnidirectional PBG width is increased 1.53 times compared with the general even one dimensional photonic crystals structure.
