In recent years, 2D layered materials, including graphene, topological insulators, transition metal dichalcogenides, black phosphorus, MXenes, graphitic carbon nitride, and metal‐organic frameworks, have attracted considerable interest due to their potential applications in the fields of physics, chemistry, biology, and energy. Their rise in the field of nonlinear photonics began around 2009 and has become an important research direction. Here, the synthesis techniques, nonlinear optical properties, integration strategies, and device applications of layered materials are reviewed. In terms of nonlinear optical properties, the focus is on saturable absorption and Kerr nonlinearity. On this basis, their applications in various pulsed lasers, including fiber lasers, solid‐state lasers, waveguide lasers, and related nonlinear optical phenomenon, are summarized. In addition, novel optical devices using layered materials, such as optical modulators, optical polarizers, optical switchers, and even all‐optical device, are also involved. It is believed that the development of 2D layered materials in the field of photonics will continue to deepen, thus laying a good foundation for its practical application.

“…Table SI summarizes some of the leading examples of vdW and their applications in different fields in the Supporting Information. It can be found that despite the explorations of different applications of vdW of 2D materials with TMs, there is limited or no report on their charge carrier and phonon dynamics, where such studies are vital in confirming the potential of such heterostructures in applications. − ,− ,− In the present study, the fabrication of vdW of bismuth telluride (Bi 2 Te 3 ), a well-known TM, with graphene, fluorographene, and molybdenum disulfide (MoS 2 ) atomic layers via a simple stacking of layers over a few layers of TM is achieved. These three different 2D systems are considered to form heterostructures with the TM and due to the difference in the parent properties of these layers, such as one is a semimetallic 2D system (graphene , ), the second one is a semiconducting defective 2D system (flurographene , ), and the third one is a 2D semiconductor with excitonic carriers (MoS 2 ).…”

Hybridizing topological materials (TM) with twodimensional (2D) materials has resulted in interesting structures, such as van der Waals heterostructures (vdW), having potential in optoelectronics. However, the performance of devices made out of such structures relies on the charge carrier interactions among the layers, which establishes the basic trade-off between the kinetically controlled charge carrier dynamics at the interface and the performance of vdW-based devices. In this perspective, three vdW are fabricated using a wet transfer technique, and the structures are probed to study the charge carrier and phonon dynamics among the TM (a few layered Bi 2 Te 3 ) and 2D systems. The three different vdW fabricated in this article are graphene/Bi 2 Te 3 (G/BT), fluorographene/Bi 2 Te 3 (FG/BT), and monolayer MoS 2 /Bi 2 Te 3 (MS/BT). Raman spectroscopy establishes the formation of all of these vdW and indicates the occurrence of the charge transfer (CT) phenomenon among them, which is further probed using ultrafast pump−probe spectroscopy. The charge carrier and phonon dynamics reveal the presence of the occurrence of the CT mechanism in all of the vdW. These spectra are further used to model the bands between different types of heterointerfaces, such as the Schottky junction between graphene and Bi 2 Te 3 and the type II heterojunction between FG/BT and MS/BT. With the help of band alignment and charge carrier and phonon dynamics studies presented, a unique CT mechanism and excitonic peak tunability in vdW are proven, where such information is essential in developing highly sensitive optoelectronic and spintronic devices
