基于传递矩阵方法和光局域化原理, 本文研究了一维反铁磁光子晶体共振频率附近光学双稳态效应随电磁波入射角、 外磁场强度及电介质层数的变化.研究发现, 当外磁场为1.0 kG(1 G=10-4 T)、电磁波小角度入射时, 反铁磁材料高低共振频率附近均可探测到光学双稳态效应; 当电磁波大角度入射时, 仅在高共振频率附近探测到光学双稳态效应. 然而, 当外磁场强度增加到2.0 kG时, 由于反铁磁材料的高低共振频率向两侧移动, 低共振频率附近缺失的光学双稳态频率窗口又被有效激发. 此外, 电磁波小角度入射时, 电介质层数在低共振频率附近对双稳态效应影响较明显.Based on the transfer matrix method and the principle of light localization, the optical bi stability (OB) changing with magnetic field strength, incident angle and dielectric layer are investigated in an one-dimensional antiferromagnetic photonic crystal near the resonant frequencies. We find that the OBs can be observed near the two resonant frequencies at a smaller incident angle, but they disappear near the higher resonant frequencies at a bigger incident angle when the magnetic field strength is 1.0 kG. However, once the external magnetic field strength increases up to 2.0 kG, the lost OB will be induced due to the the two resonant frequencies shifting towards two sides. In addition, the dielectric layers also have a greater influence on OB near the lower resonant frequencies at a smaller incident angle.
