In this work, we have studied the nonreciprocal properties of quasi-periodic Octonacci multilayer incorporating current-induced drifted graphene monolayers at the interfaces. We have analyzed the transmittance of the structure and compared it with that of regular periodic photonic crystals. Our investigation has revealed that the transmission of light is significantly improved through configurations comprising dielectric layers and graphene monolayers. The proposed structures exhibit nonreciprocal optical responses across a broad range of frequencies. The coupling of surface plasmon polaritons in the quasi-periodic structure exceeds that of periodic structures. We have examined nonreciprocal behaviors versus the drift velocity of electrons and the Fermi energy of graphene layers. It has been demonstrated that the reciprocity of the system can be adjusted by manipulating the Fermi energy and the drift velocity of the graphene layers. Moreover, the direction of nonreciprocity is dictated by the sign of the drift velocity. Nonreciprocal behavior is absent under zero DC bias and can be tuned up to 4.5 THz with bias. These distinctive properties suggest potential applications of these structures in optoelectronic devices.
