Research of One-dimensional Photonic Crystal

One-dimensional photonic crystal SiO2/TiO2 was designed to simulate and analyze its band characteristics by using theory Jones Matrix.The results showed that photonic band gap became wider and shifted to longer wavelengths because of the increase of media thickness ratio of photonic crystal and that photonic band gap was not affected by the cycle of photonic crystal.According to the optimal parameters obtained by theoretical simulation,a one-dimensional photonic band-stop filter was made.It was applied to optical communication band.Then its photonic band gap was measured,which was consistent with theoretical simulation.
