“…The performance of SAs can be enhanced by stacking van der Waals heterostructures made of different 2D materials [ 13 , 339 ]. Furthermore, the carrier migration and heat diffusion of 2D materials are confined in plane, making them possess specific optical and electrical properties, such as quantum Hall effect and ultrahigh carrier mobility [ 378 , 379 , 380 ]. However, the study of 2D materials started relatively late, and there are still many potential areas to be further explored.…”

Owing to their extraordinary physical and chemical properties, two-dimensional (2D) materials have aroused extensive attention and have been widely used in photonic and optoelectronic devices, catalytic reactions, and biomedicine. In particular, 2D materials possess a unique bandgap structure and nonlinear optical properties, which can be used as saturable absorbers in ultrafast lasers. Here, we mainly review the top-down and bottom-up methods for preparing 2D materials, such as graphene, topological insulators, transition metal dichalcogenides, black phosphorus, and MXenes. Then, we focus on the ultrafast applications of 2D materials at the typical operating wavelengths of 1, 1.5, 2, and 3 μm. The key parameters and output performance of ultrafast pulsed lasers based on 2D materials are discussed. Furthermore, an outlook regarding the fabrication methods and the development of 2D materials in ultrafast photonics is also presented.

“…[193][194][195][196][197] In the past few years, optical modulators based on 2DMs have been an extensive research topic and great progress has been made. [198][199][200][201][202] Specifically, 2DMs optical modulators such as mode-locked fiber lasers, [203,204] Q-switching lasers, [205,206] saturable absorbers, [207,208] polarization controllers, [209] and wavelength converters [210] have already been demonstrated. For example, graphene mode-locked fiber lasers that generated pulse light with an ultrashort duration were achieved.…”

With the development of novel optoelectronic materials and nanofabrication technologies, integrated photonics is a rapidly developing field that will promote the development and application of next‐generation photonic devices. In recent years, emerging two‐dimensional materials (2DMs) including graphene, transition metal dichalcogenides (TMDCs), black phosphorus (BP), and ternary compounds show many complementarities and unique characteristics over those of traditional optoelectronic materials including broadband absorption, ultrafast carrier mobility, strong nonlinear effects, and compatibility for monolithic integration. Herein, the recent progress on waveguide‐integrated active devices for a full photonic circuit based on 2DMs is reviewed. Both the development of nanofabrication techniques and the working mechanism of active photonic components based on 2DMs containing integrated light sources, waveguide‐integrated modulators, photodetectors, as well as some advanced 2DMs‐based optoelectronic devices are illustrated in detail. In the end, the existing challenges and perspectives on novel 2DMs‐integrated photonics are summarized and discussed.

“…Because intercalation cations such as NH 4 + and K + can facilitate etching and exfoliation, fluorohydrides (e.g. NH 4 HF 2 and KHF 2 ) are also popular etchants for fabricating MXenes [191]. Table 1 shows a summary of fabrication methods for SAs.…”

AbstractSince graphene was first reported as a saturable absorber to achieve ultrafast pulses in fiber lasers, many other two-dimensional (2D) materials, such as topological insulators, transition metal dichalcogenides, black phosphorus, and MXenes, have been widely investigated in fiber lasers due to their broadband operation, ultrafast recovery time, and controllable modulation depth. Recently, solution-processing methods for the fabrication of 2D materials have attracted considerable interest due to their advantages of low cost, easy fabrication, and scalability. Here, we review the various solution-processed methods for the preparation of different 2D materials. Then, the applications and performance of solution-processing-based 2D materials in fiber lasers are discussed. Finally, a perspective of the solution-processed methods and 2D material-based saturable absorbers are presented.
