Paper Abstract

A new kind of tunable multi-channel wavelength demultiplexer (WDM) based on metal-insulator-metal (MIM) plasmonic nanodisk resonators with a metal block is proposed. The transmission properties of such structure are simulated by the Finite-Difference Time-Domain (FDTD) method, and the eignwavelengths of the disc resonator are calculated theoretically. It is found that the transmission characteristics of the filter can be easily adjusted by changing the geometrical parameters of the metal block of the nanodisk. The multi-channel WDM structure consisting of a plasmonic waveguide and several nanodisk resonators with metal block, by changing the parameter of metal block of nanodisk resonators, the filter shows the resonant mode filter function. Basing on this characteristic, a three-port wavelength demultiplexer is designed, which can separate resonant modes inside the nanodisk with high transmission up to 60%. It can find important potential applications in highly integrated optical circuits.
