## Description

- description: The unique optical properties of two-dimensional layered materials
    are attractive for achieving increased functionality in integrated photonics.
    Owing to the van der Waals nature, these materials are ideal for integrating with
    nanoscale photonic structures. Here we report on carefully designed air-mode silicon
    photonic crystal nanobeam cavities for efficient control through two-dimensional
    materials. By systematically investigating various types and thickness of two-dimensional
    materials, we are able to show that enhanced responsivity allows for giant shifts
    of the resonant wavelength. With atomically precise thickness over a macroscopic
    area, few-layer flakes give rise to quantization of the mode shifts. We extract
    the dielectric constant of the flakes and find that it is independent of the layer
    number down to a monolayer. Flexible reconfiguration of a cavity is demonstrated
    by stacking and removing ultrathin flakes. With an unconventional cavity design,
    our results open up new possibilities for photonic devices integrated with two-dimensional
    materials.
