Manipulate Quantum Emission by Interface States between Multi-component Moiré Lattice and Metasurface

Abstract

In recent years, moiré lattice has become a hot topic and inspired the research upsurge of moiré lattice. In this work, we propose a method of constructing a multi-composite moiré lattice, which is composed of over three periodic component structures. Moreover, we propose the moiré lattice-metasurface structure, which can realize the multi-wavelength interface states between these kinds of moiré lattices and metasurfaces. The wavelength, polarization, and number of moiré 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.
