In this paper, we propose a plasmonic circuit based on optical add‐drop multiplexer. A stack of silicon–graphene–gold layers is used at optical add‐drop filter ends. The light input from a laser source at the silicon base of the stack enables ultrafast electrical switching by rapid light‐electron energy conversion. It allows feedback signals monitoring by the output mobility visibility, which is useful for system control. Certain results show ultra‐fast switching time of ~ 5.0 fs at a stable power of 3 mW. The results further demonstrate great avenues for the secured communication channel‐based on the plasmonic electronic circuit.
