چکیده
|
We propose an innovative 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 and the well-known hybrid modes of a hybrid metal-dielectric waveguide. our results demonstrate that the hybrid structure results in up to 5 times enhancement in the spp beam intensity relative to the conventional design of slit-groove nanostructure. this new design of spp based nano source can be applied in many applications including nano photonic devices.
