- Abstract
Switching of a single plasmon interacting with n equally spaced quantum dots coupled to one-dimensional surface plasmonic waveguide is investigated theoretically via the real-space approach. We showed that the transmission and reflection of a single plasmon can be switched on or off by dynamically tuning and changing the number of the equal transition frequencies of the quantum dots. Increasing the number of doped quantum dots having the equal transition frequencies results in the wide-band reflection of a single plasmon and the complete transmission peaks near the resonant frequencies.
