We demonstrate a classical analogue of electromagnetically inducedtransparency (EIT) in a highly flexible planar terahertz metamaterial (MM)comprised of three-gap split ring resonators. The keys to achieve EIT in thissystem are the frequency detuning and hybridization processes between twobright modes coexisting in the same unit cell as opposed to bright-dark modes.We present experimental verification of two-bright mode coupling for aterahertz EIT-MM in the context of numerical results and theoretical analysisbased on a coupled Lorentz oscillator model. In addition, a hybrid variation ofthe EIT-MM is proposed and implemented numerically in order to dynamically tunethe EIT window by incorporating photosensitive silicon pads in the split gapregion of the resonators. As a result, this hybrid MM enables the potentialactive optical control of a transition from the on-state (EIT mode) to theoff-state (dipole mode).
