“…These efforts have greatly promoted the development of few‐layer MoS 2 in mode‐locked lasers and achieved a lot of important results . Similar to MoS 2 , layered WS 2 also has a direct bandgap and exhibits excellent nonlinear optical properties . For example, the researchers demonstrated the soliton mode‐locked fiber lasers using WS 2 nanosheets, which were prepared by the liquid phase exfoliation and pulsed laser deposition method, respectively, as shown in Figure a–f.…”

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.

in the field of ultrafast photonics. Since the successful demonstration of graphene-based saturable absorber (SA) for ultrafast pulsed lasers, [7,8] 2D layered materials including black phosphorus, topological insulators, and transition metal dichalcogenides (TMDs), have recently been extensively investigated in nonlinear optical devices for the generation of ultrafast pulses via passive modelocking operation. [10][11][12][13][14][15][16][17][18][19][20][21][22][23] In particular, the recent advancements in the development of TMDs with unique electronic and optical attributes have explored many potential applications in electronics and photonics. [24,25] The TMDs with layered structure can be exfoliated into atomic-thin layers, which advance the development of wider applications as high-performance transistors, photodetectors and nonlinear optical devices owing to their widespread bandgaps from the visible to the nearinfrared region. [24][25][26][27][28][29][30][31] Currently, nonlinear optical devices based on group VIB TMDs have been fully studied using as saturable absorbers (SA) for the successful generation of short pulses in broadband region. [17][18][19][20][21][22][23][32][33][34][35][36] Despite the previous efforts, it is still possible to optimize the SA devices toward ultrafast photonics for the admired purposes of generating laser pulse with shorter pulse width and greater output power, which can be anticipated by exploring other members of TMDs. In comparison with intensively studied group VIB TMDs, group IVB TMDs which are theoretically predicted to have superior physical properties to group VIB TMDs, have rarely been investigated yet. [37,38] For instance, single-layered HfS 2 is expected to possess much higher carrier mobility (≈1800 cm 2 V −1 s −1 ) and smaller bandgap (≈1.2 eV) than that of MoS 2 . [38,39] Owing to superior electronic properties, ultrathin HfS 2 fabricated by mechanically exfoliation or chemical vapor deposition methods presents significant potential in phototransistors and field-effect transistors. [40][41][42][43][44][45][46][47] However, to our knowledge, the nonlinear optical properties of HfS 2 and its application in ultrafast photonics remain unknown.In this contribution, we demonstrate a new function of multilayered HfS 2 nanosheets (NSs) with nonlinear optical absorption for development of ultrafast photonic devices. We prepared HfS 2 NSs via a modified liquid exfoliation approach using isopropanol (IPA) as solvent. HfS 2 dispersions are precisely deposited onto a microfiber to form a SA device by using a photonic crystal fiber (PCF) assisted deposition method. The HfS 2 SA device is found to show excellent nonlinear absorption Group IVB transition metal dichalcogenides (TMDs) have attracted significant interests in photoelectronics due to their predictable superior physical properties compared to group VIB (Mo and W) TMDs. However, the nonlinear optical properties and ultrafast photonic devices based on group IVB TMDs remained unexplored so far. Herein, the nonlinear ...

Abstract.We have developed and approved experimentally a passively Q-switched erbium-doped fibre laser. It is based on the saturable absorption of graphene oxide solution deposited around a microfibre waveguide. The microfibre is fabricated using a standard flame-brushing technique. By controlling the pump power in the cavity, the fibre laser can produce microsecond Q-switched pulses at 1529 nm with the maximum repetition rate 53.47 kHz. With a pumping power of 105.98 mW at 980 nm, each of the laser pulses has the energy about 0.78 nJ and the maximum output power is 42.15 μW.
