Abstract
A stop-band filter is discussed based on the strong coupling-like phenomenon in metal-insulator-metal (MIM) structures involving molecular J-aggregates. The structure is composed of a [Formula: see text]-shaped resonator, an input waveguide and an output waveguide. The finite element method (FEM) method is employed in simulation. The results show that the strong coupling phenomenon appears with the Molecular J-aggregates. The small variations in size of the whole structure have little effect on stop bandwidth of the transmission spectrum and the stop bandwidth of the transmission spectrum in the designed structures is mainly determined by the oscillation strength of molecular J-aggregates. The larger the oscillation length of molecular J-aggregates part is, the wider the stop-band is.
