ABSTRACT
This chapter aims to emphasise chip-integrated nanophotonic structures, including waveguides, photonic crystals and resonators, which could provide a much better platform to enhance light–matter interactions in Two-dimensional (2D) materials and construct high-performance optoelectronic devices. Determined by the unique electronic band structure and stacking-order-dependent interlayer coupling, 2D materials also have outstanding non-linear optical properties. The surface plasmonic mode around metal nanostructures is another attractive architecture to enhance the coupling between 2D materials and the optical field. A number of spectroscopy studies have been implemented on 2D material-Planar photonic crystals (PPC) cavities and demonstrated strongly enhanced light–matter interactions in 2D materials over the optical absorption, Raman scattering, light emission and non-linear processes. The PPC cavity-enabled strong Purcell effects can not only be used to enhance photo-luminescence emission from 2D materials but also promise the improved efficiency of light-emitting devices assembled from 2D materials.
