Tunable Multi-Band-Stop Filters Using Generalized Fibonacci Photonic Crystals for Optical Communication Applications

In this study, a numerical investigation of photonic quasi-periodic Generalized Fibonacci (GF) (m, n) sequences is carried out in the visible spectrum. The transfer matrix method employed to study behavior wave propagation through structures. Firstly and highlight importance GF structure, its transmittance spectrum compared those periodic ordinary It shown that structure permits one obtain multi-photonic band gaps (PBGs) separated by several resonance modes. variation parameter m 1) allows for tuning number, position width these bands. By changing m, wavelengths (650, 850, 1300, 1550 nm) plastic glass optical fibers can be allowed or forbidden transmit according value parameter. contrast, n (1, hides all PBGs only appearance Kiessig fringes. proposed structures find application as tunable multi-band-stop filters fiber wavelengths.
