Paper Abstract

The hybrid rib-slot-rib surface plasmon waveguide where a combined rib-slot-rib structure is added on the metal substrate within a low-index gap region with asymmetric structures is proposed using finite element method. Two types of asymmetric structures are introduced and their modal properties are discussed and compared to their traditional long range surface plasmon waveguide. Our designed structures can provide enhanced confinement energy within the gap region at proper parameters. Our simulation result is a guide for turning properties of plasmonic waveguide and providing ways for improved electromagnetic energy confinement in surface plasmon waveguide.
