Microelectromechanical Systems–Tunable Reflective Metalenses for Switchable Focusing between Two Arbitrary Phase States
) at their optimal wavelength, persistent dynamic functionalities throughout the spectral range of 650-850 nm, and fast switching with rise/fall times of 0.58/0.4 ms. The developed MEMS-tunable ML platform enables truly arbitrary, dynamically controlled dual-phase-map switching and can straightforwardly be extended to feature other dynamic functionalities, thereby enriching the portfolio of already developed compact, advanced, and dynamic optical systems.
