Electromagnetically Induced Transparency (EIT) and strong coupling are pivotal phenomena in light-matter interactions with profound implications for quantum and material sciences. EIT, resulting from destructive interference in three-level quantum systems, creates a transparency window within an absorption spectrum [1] and is classically emulated in metamaterials via bright-dark-mode interference. This enables applications such as slow-light devices, sensors, and cloaking technologies. Strong coupling, achieved when the interaction strength between a quantum emitter and an electromagnetic field surpasses system losses, leads to hybridized states (Rabi splitting), facilitating coherent energy exchange and insights into coupling mechanisms [2]. This study combines these phenomena using terahertz metamaterials to achieve tunable transitions between single and dual EIT states through strong coupling. This integration enhances the tunability of metamaterial-based devices and deepens our understanding of EIT and strong coupling, bridging classical and quantum perspectives for future applications.
