This Surface plasmon polaritons (SPPs) refer to a special electromagnetic wave mode that exists at the interface between a metal and a dielectric, holding significant application prospects in on-chip devices. However, relevant on-chip modulation devices are quite scarce, especially in the terahertz (THz) band. In this paper, by integrating metasurfaces with photoresist, a terahertz on-chip modulation device is designed, enabling the control of the propagation of surface plasmon polaritons. This terahertz on-chip modulator provides a reference for the design of novel surface plasmon polariton devices and exhibits broad application prospects in future photonic integrated chips.
