Controlling the electromagnetic waves at an ultrafast time scale is of paramount importance for various applications, including ultra-high-speed switches, routers, high harmonic generation, and many more. To achieve this, we aim to integrate metamaterial with emerging quantum materials (see the above figure). Metamaterial brings flexibility in controlling the amplitude, polarization, phase, and frequency of electromagnetic waves, while quantum material offers unprecedented control over the features of metamaterials at ultrafast timescales (from picosecond to femtosecond).
