Abstract

The invention discloses a switching rate adjustable electric signal routing device based on a coupling topology edge state, and relates to the technical field of electronic information. The topological circuit module is formed by connecting two first resonator sub-arrays and second resonator sub-arrays which are identical in structure and have topological edge states through a third coupling element, so that the topological edge states of the two sub-arrays are mutually coupled to form symmetrical and antisymmetric coupling topological edge states. The input port and the first output port are respectively connected with the position of the topological edge state of the first resonator subarray, and the second output port is connected with the position of the topological edge state of the second resonator subarray. The function of switching signals to the first output port or the second output port for output at different switching rates is achieved by adjusting the voltage of the excitation signal. The invention has the advantages of no need of adding control signals, simple structure and strong robustness based on a topology protection mechanism.
