چکیده
|
The perfect plasmon-induced absorption (pia) effect is achieved in a simple plasmonic system, composed of two rectangle cavities side-coupled to the metal-insulator-metal (mim) waveguide with a barrier. the transmission properties of the system are calculated by the finite-difference time-domain (fdtd) method and theoretically explained by the three-level plasmonic system. more interestingly, the broadband absorption window will be splitted into double windows by adding another rectangle cavity resonator, and the physical mechanism is presented. at the same time, multi-switching effect is also discovered. undoubtedly, the proposed novel structures have potential application in highly integrated optical circuit and can be simply fabricated.
