| 摘 要： | 为设计可调控的光开关, 本文设计了基于石墨烯的超材料和一维光子晶体的复合结构,应用传输矩阵法研究它的传输特性.石墨烯超材料的吸收和各向异性的特性导致结构的传输对电场极化方向特别敏感.通过电场极化方向的旋转,可以动态调节电磁波的透射和吸收,也可以实现电磁波从全透射到全反射或者全吸收的完全转化.

| Abstract: | In order to design tunable optical switch, a compound structure composed of one-dimensional photonic crystal and graphene metamaterial is designed.The transmission properties of the designed structure are studied through transfer matrix method.The absorption and anisotropy of graphene metamaterial lead that the transmission is dependent on the polarization direction.Through the rotation of polarization direction, the transmittance and absorption can be dynamically adjusted, and the total transformation from the transmission to reflection or absorption can be also achieved. |

| Keywords: | optical switch graphene metamaterial one-dimensional photonic crystal polarization |
