Microcavities concentrate light in tiny volumes and are important, e.g., for semiconductor lasers and nonlinear optics. In this paper, metasurfaces are introduced to realize microcavities with arbitrary mode profiles.

The angular dependence is a well-known issue in metasurface engineering. Here the authors introduce a supercell metasurface able to implement multiple independent functions under large deflection angles with high efficiency, leading to a wavelength t

We demonstrate telecom-wavelength microcavities stabilized by dielectric metasurfaces. The approach achieves microcavities with quality factors exceeding 3300 using prevalent semiconductor manufacturing processes and opens the near-arbitrary field co

We demonstrate stable optical microcavities by counteracting the phase evolution of the cavity modes using an amorphous silicon metasurface as one of the two cavity end mirrors. Careful design allows us to limit the metasurface scattering losses at t
