Abstract: This article reports the design and numerical analysis of a metal-insulator-metal plasmonic directional coupler. The directional coupler design can be used in the concept of the Step impedance resonators (SIRs); thus only one design is needed for dual-band action in both of the optical bands. Therefore, the structure development in the improved architectures pertaining to filtering as well as multiplexing devices are necessary for end of these kind of specifications without reducing the dimensions of the subsystems. The proposed coupler can be used in both optical bands 1299-nm (O) & 1629-nm (L). The directional coupler design works very well in the improvement of photonic integrated circuits (PICs) and also it can be mixed with existing silicon based photonic circuits.
