摘要
设计了一种可调的等离子体诱导透明(PIT)效应的双槽谐振器的金属-绝缘体-金属(MIM)表面等离子体波导结构。利用微腔共振模式实现对表面等离子体在波导中传输操控。分别改变槽的长度,两槽之间的距离和槽填充材料的介电常数实现特定滤波效应,结合电场分布分析表面等离子体在波导中共振产生的电磁诱导透明现象,并设计动态可调的等离子体诱导透明效应器件。利用有限元法(FEM)对设计进行数值模拟。
The tunable plasmonic-induced transparency (PIT) is proposed numerically in the plasmonic system composed of dual unsymmetrical resonators shaped metal-insulator-metal (MIM) waveguide. The specific filtering effects are realized by changing the length of the groove and dielectric constant. The phenomena of the plasmonicinduced transparency caused by the surface plasmonic resonance in the waveguide are analyzed according to the electric field distributions. The finite element method (FEM) method is conducted to verify numerical simulation. The structure is applied widely in optical communication, integrated optics, and lithography.
