Characteristics of surface plasmon polaritons in a dielectrically chiral-metal-chiral waveguiding structure
Abstract:
We demonstrate theoretically the characteristics of surface plasmon polaritons (SPPs) with an asymmetric chiral-metal-chiral (CMC) waveguide structure, under realistic frequency dependencies of the permittivity and chirality parameters. Generalized dispersion relations are derived which can be applied to the nonchiral SPPs. We find that the existence of cutoffs in different modes for the CMC structures may facilitate the design of mode-selective surface plasmon waveguides. CMC-SPPs also exhibit an interesting dependence of the polarization on the chiral strength. These novel characteristics of CMC-SPPs provide new possibilities for the design of more compact nanophotonic devices.

Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...
