Abstract
We report the transmission response of generalized Fibonacci photonic crystal Fl(m;n) in microwave domain for normal incidence, where l is the generation number, and m and n are parameters of the Fibonacci distribution. The transmission spectra are calculated through the transfer matrix method and studied by varying the Fibonacci parameters. The structure is exploited to design selective optical fllters with narrow passbands and polychromatic stop band fllters. Therefore, other structure conflgurations based on the generalized Fibonacci system are proposed. A juxtaposition of p multilayer systems built according to Fibonacci distribution (Fl(m;n)) p makes possible to have switch-like property (ofi-on-ofi-on-ofi-on-...). Then, a hybrid structure obtained by sandwiching stacks of generalized Fibonacci photonic crystal between two periodic photonic crystals is proposed to enlarge the photonic band gap in microwave domain.
