Metaoptics formed by ultrathin, planar building blocks enables compact and efficient optical devices that manipulating light at the nanoscale. The development of tunable metaoptics holds the promise of miniaturized, efficient optical systems that can dynamically adapt to changing conditions or requirements, propelling innovations in fields ranging from telecommunications and imaging to quantum computing and sensing. Two-dimensional (2D) materials are unique and active in enabling tunable metaoptics due to their exceptional electronic and optical properties brought by the quantum confinement within the atomically thin layers. In this review, we discuss the recent advancements and challenges of 2D materials towards tunable metaoptics in both linear and nonlinear regimes and provide an outlook for prospects in this rapidly advancing area.
