Abstract

We propose a metal-insulator-metal (MIM) waveguide structure in which the plasma-induced transparency (PIT) effect is based. Using the finite-difference in time domain (FDTD) method, the designed structure was simulated in two dimensions. It obtains both narrowband PIT peaks, both with more than 90% absorption. In addition, we use the Kerr material filled in the cavity for tuning, and we can find that the transmission spectrum shifts with increasing pump light intensity. The proposed structure can be applied to filter. The proposed structure has important prospects for application in integrated optical devices.
