摘　　要：A compact high-resolution structure for plasmonic wavelength demultiplexers with cascading square resonators is proposed and demonstrated numerically by using the two-dimensional finite element method.It is found that the full width at half maximum of the transmission spectrum can be narrower(~10 nm)than any results reported before.The simulation results can be explained by the temporal coupled-mode theory.This structure can be easily extended to 1×N channels,which has an important role in the wavelength division multiplexing system in nanoscale.
