▎ 摘　　要

Magneto-optical properties of a one-dimensional (1D) photonic crystal with a graphene defect layer is investigated. It is shown that the steady-state behavior of the medium completely depends on the intensities of magnetic and coherent coupling fields. By proper chose of the controllable parameters, it is found that the absorption spectrum of 1D photonic crystal can be adjusted easily. In addition, by controlling the magnetic field and Rabi-frequencies of applied lights, the transmitted and reflected light pulses at the infrared region can be tuned. The effect of magnetic and coupling fields on the transmission and reflection properties of the laser pulse at lambda 0=9 mu m of the medium is also studied. It is found that optical bistability in reflection and output fields can be controlled by applying the magnetic and coupling fields. The proposed model may provide some new possibilities for technological applications in optoelectronics, solid-state quantum information science and systems, due to vast applications in signal processing.
