Plasmonic functional elements are promising to combine the advantages of photonics and electronics – high speed and small spatial extent. We employ numerical simulations and an analytic approach based on transmission line theory to demonstrate several functional elements that consist of so called stub structures – terminated ends on metal–insulator–metal waveguides.
Splitters are presented that allow arbitrary adjustment of the transmission ratio from an input to two different output arms; frequency filters are designed that provide steep transmission resonances; and, finally, nanoscale all-plasmonic switching is proposed with an operating frequency of more than 20 THz.
The suggested device components are promising for future applications in ultrafast nanoscale information processing.
