Abstract

Two-dimensional (2D) layered materials such as graphene, transition metal dichalcogenides (TMDs), and hexagonal boron nitride have attracted considerable attention due to their exotic physical properties and potential for diverse applications [1]. To further utilize the optical properties of TMDs, microcavities can be used to enhance the light-matter interaction [2]. Compared to the successful use of TMDs as an active material within microcavities, it is a challenge to control the cavity modes with 2D materials. Because of the atomically thin nature, cavity modes are barely affected and the resonant wavelength can only be tuned slightly [3,4]. With atomically precise thickness over macroscopic areas and extensive compatibility offered by van der Waals interface, photonic devices controlled through single atomic layers would present a new direction in nanotechnology. Cavity structures designed specifically for enhanced sensitivity to ultra-thin materials is required to unravel the full functionality and capability of the TMD/cavity hybrids.
