Abstract: (6568 Views)
We propose a new design for metallic slit-groove nanostructure to increase the propagation intensity of a unidirectional surface plasmon polariton (SPP) light beam. Our idea is based on the combination of the concept of unidirectional plasmonic wave propagation in a metallic slit-groove nanostructure with the well-known hybrid modes of a hybrid metal-dielectric waveguide. We show that this novel structure results in up to 5 times enhancement in the SPP beam intensity relative to the conventional design of slit-groove nanostructure.
Keywords: Surface plasmon polariton(SPP), Hybrid plasmonic waveguide, Metallic slit-groove nanostructure
