Summary: Electromagnetically induced transparency (EIT) effect provides a vast space for the development of new optical devices. This study proposes and verifies an all-dielectric metamaterial based on the EIT effect. The amplitude and resonant frequency of the transmission window can be actively controlled, and the group delay can be switched. The frequency selectivity can be achieved by changing the diameter of the silicon array, and the resonant frequency can be shifted by immersing the sample in oil with different refractive indices. The metamaterial sample shows potential applications in various fields such as light buffering, 6G/terahertz communications, and ultrafast devices.
