Tunable asymmetric Mach-Zehnder interferometer based on spoof surface plasmon polaritons
{{output}}
In this paper, an ultrathin asymmetric Mach-Zehnder interferometer (MZI) based on spoof surface plasmon polaritons (SSPPs) is proposed. The asymmetry in the MZI structure induces a phase difference between the SSPPs waves propagating in the upper and lower arm... ...
