Abstract

In recent years, moir\'e lattice has become a hot topic and inspired the research upsurge of moir\'e lattice. In this work, we propose a method of constructing a multi-composite moir\'e lattice, which is composed of over three periodic component structures. Moreover, we propose the moir\'e lattice-metasurface structure, which can realize the multi-wavelength interface states between these kinds of moir\'e lattices and metasurfaces. The wavelength, polarization, and number of moir\'e interface states can be manipulated flexibly, with anisotropic metasurfaces. These multi-wavelength interface states are employed to enhance quantum emission (QE) and over 20 times QE efficiency can be obtained.
