A photonic time crystal is an optical system of which properties such as its refractive index are modulated strongly and rapidly over time. One has now been obtained all-optically by delivering an intense terahertz light wave onto a material with a specialized microstructure that hosts collective waves of electrons known as plasmons.Ultrafast temporal engineering of optical properties using terahertz light
