摘要

A compact wavelength demultiplexer (WDM) with tunable high resolution based on metal–insulator-metal (MIM) plasmonic ring resonators is proposed and numerically investigated using the finite element method (FEM). The simulation results show good agreement with theoretical analysis. The resonant wavelength of the WDM can be easily tuned by adjusting the geometrical parameters of the structure and the refractive index of the dielectric material in the ring resonator. The proposed demultiplexer can separate two wavelengths with a spacing of 9 nm. Furthermore, the transmission spectrum of the multi-ring cavity demultiplexer is systematically studied, revealing a trade-off between high resolution and high transmission power. This WDM shows great potential for applications in highly integrated optical circuits.
