We demonstrate that, by an appropriate choice of the taper angle, we can effectively suppress the mode attenuation achieving the effective power transfer in both linear and nonlinear couplers.Keywords: Nano scale; Nonlinear coupler; Nonlinear switching; Plasmonic; Power transfers; Surface plasmon polaritons; Taper angles; Tapered waveguide; Electric losses; Electromagnetic wave polarization; Natural language processing systems; Plasmons201110.1109/NLP.2011.61026552016-02-24
