2D Layered Materials: Synthesis, Nonlinear Optical Properties, and Device Applications

摘要

In recent years, 2D layered materials, including graphene, topologicalinsulators, transition metal dichalcogenides, black phosphorus, Mxenes,graphitic carbon nitride, and metal-organic frameworks, have attractedconsiderable interest due to their potential applications in the fields ofphysics, chemistry, biology, and energy. Their rise in the field of nonlinearphotonics began around 2009 and has become an important researchdirection. Here, the synthesis techniques, nonlinear optical properties,integration strategies, and device applications of layered materials arereviewed. In terms of nonlinear optical properties, the focus is on saturableabsorption and Kerr nonlinearity. On this basis, their applications in variouspulsed lasers, including fiber lasers, solid-state lasers, waveguide lasers, andrelated nonlinear optical phenomenon, are summarized. In addition, noveloptical devices using layered materials, such as optical modulators, opticalpolarizers, optical switchers, and even all-optical device, are also involved. It isbelieved that the development of 2D layered materials in the field of photonicswill continue to deepen, thus laying a good foundation for its practicalapplication.
