Abstract

Abstract Spoof surface plasmon polaritons (SPPs) with strong subwavelength field confinement and enhancement offer a promising way for realizing integrated on‐chip terahertz (THz) devices. How to find a simple way to control the dispersion of spoof SPPs and then achieve functional on‐chip devices is thus highly desired. Here, the authors theoretically and experimentally demonstrate that such a method can provide sufficient design degrees of freedom to enable versatile THz spoof SPP metadevices. As a proof‐of‐concept demonstration, a series of on‐chip meta‐devices including the switch, the wavelength demultiplexer, and the splitters are presented. The proposed strategy paves a simple way toward the integrated on‐chip THz devices with various functionalities.
