Abstract
Nonlinear optics plays an essential role in various photonic and optoelectronic applications, such as wavelength conversion and information processing. Recently, the extraordinarily large nonlinear optical properties of two-dimensional layered materials have attracted significant attention. However, the conversion efficiency of two-dimensional layered materials is typically limited by the atomically thick light-matter interaction length. Here, I will discuss the strategies to enhance optical nonlinearities of two-dimensional layered materials (e.g., graphene and transition metal dichalcogenides) for various integrated photonic and optoelectronic applications, such as high-purity quantum emitters, wavelength converters, and ultrafast lasers. I will also present our recent results of employing hybrid structures, such as mixed-dimensional heterostructures, plasmonic structures, and silicon/fibre waveguides integrated structures.
