Study on the Transmission Properties of Fibonacci One-Dimensional Photonic Crystal Nanometer Films in Visible Region
|
Abstract:
In order to study the transmission properties of one-dimensional photonic crystal nanometer films with Fibonacci sequence in visible region,the transfer matrix method (TMM) is used to analyze the transmission coefficients changing with frequencies in various cases.The numerical results show that in the normal incidence the transmission property is influenced by the Fibonacci sequence terms,physical thickness,initial order and the refractive index difference of the component,and the more the refractive index difference,the easier the wide forbidden band will exist in the visible light area.The further studies on the transmission properties of generalized Fibonacci sequence one-dimensional photonic crystal nanometer films are also done and the results show that they are easier to form band gap than the typical situation in the visible region.
