چکیده
|
We propose a plasmonic structure based on the metal-insulator-metal waveguide with the side-coupled isosceles trapezoid cavities. both of the structures based on the side-coupled trapezoid cavities separated or connected with waveguides can realize the plasmon-induced transparency (pit). by adjusting the structure parameters, the off-to-on pit response can be tunably achieved. the coupled mode theory (cmt) method is used to study the pit phenomenon and explain the transmission characteristics. this work provide a potential way for designing highly integrated photonic devices.
