| Summary: | Terahertz (THz) communication is a rapidly advancing field with applications spanning space exploration, wireless communication, and security checks. Achieving effective intensity modulation of THz radiation is a crucial requirement for THz technology. In this study, we propose an approach to achieve real-time and precise control over THz radiation using a gold split-ring metasurface integrated with MoS<sub>2</sub> layers. We demonstrate the emergence of an electromagnetically induced transparency-like resonance through optical pumping, resulting in high-quality THz signal transmission with impressive modulation depth of 81% at 612 GHz. These findings hold great promise for a wide range of THz applications, including sensing, switching, and filtering. |
