“…As a matter of fact, several groups have already claimed the broadband operation of a single SA based on its experimental characterizations at a few discrete wavelengths: 500 nm broadband operation based on 1030 and 1558 nm characterizations, [ 89 ] and 1000 nm broadband operation based on 1035, 1564, and 1908 nm characterizations. [ 90 ] This indicates that our realized V 4 C 3 MXene‐based SA could have an ultra‐broad operating bandwidth of not less than 350 nm. Our results show that V 4 C 3 MXene could be a strong candidate for ultra‐broadband nonlinear photonic devices, including optical communications, medical, and military technology operating at the SWIR wavelength region.…”

Large optical nonlinearity at short‐wavelength‐infrared (SWIR) has enabled 2D MXene to be used explosively in ultrafast nonlinear photonics and optoelectronics. Despite the high technological interest in V4C3 MXene in electrochemistry, investigations from a nonlinear photonics perspective have yet to be conducted. Here, the nonlinear optical characteristics of V4C3 MXene at SWIR wavelengths are systemically investigated. First, Z‐scan measurements are performed and the saturated absorption and self‐defocusing properties of V4C3 MXene at both wavelengths of 1560 and 1910 nm are observed. Density functional theory calculation shows metallic characteristics of V4C3 MXene. Based on the saturable absorption properties of V4C3 MXene, a single saturable absorber (SA) operating at both wavelengths of 1560 and 1910 nm is experimentally implemented. Stable mode‐locked pulses of 638 fs pulse duration at 1559.9 nm are produced instantaneously from an erbium‐doped fiber ring cavity using SA. The same SA generates 1.08 ps mode‐locked pulses at 1911.9 nm from the thulium holmium co‐doped fiber ring cavity. This indicates that the operating bandwidth of this realized V4C3 MXene‐based SA could be at least 350 nm. This work strongly suggests that V4C3 MXene can serve as an ultra‐broadband and high‐performance nonlinear optical material platform in the SWIR regions.

“…[23][24][25][26][27] Till now, researchers have utilized graphene to obtain pulses, with a wavelength ranging from 800 to 4400 nm, implying the broadband properties of graphene. [28][29][30][31][32][33] Nevertheless, there are some drawbacks of graphene. For instance, the relatively low modulation depth and saturation intensity limit the energy of the pulsed lasers based on graphene SAs.…”

“…With the advantages of broadband saturable absorption and ultrafast recovery time, graphene was soon widely implemented in ultrafast pulsed lasers. [40][41][42][43] TIs can adjust the bandgap by varying the thickness, which makes them fascinating in optoelectronics. [44,45] TMDs are a kind of semiconductor nanomaterial, which have a sandwich structure with two layers of chalcogen interspersed with a layer of transition metal.…”

Nanomaterials with remarkable optical, mechanical, and electrical properties have shed new light on various fields including optoelectronics, sensors, biomedicine, and ultrafast photonics. Particularly, owing to their nonlinear optical properties, fast recovery time, and broadband operation, nanomaterials are well qualified as saturable absorbers in ultrafast pulsed lasers. Over the development of the past decades, various nanomaterials have been developed as saturable absorbers, which contribute to a diversity of lasers with excellent performance. Therefore, it is important for researchers to provide a landmark of the applications of nanomaterials in ultrafast photonics concerning cutting‐edge development. Herein, the integration and applications of nanomaterials in ultrafast photonics are reviewed. First, end‐face, lateral, as well as photonic crystal fibers padding integration methods are introduced along with their process and characteristics. Then the ultrafast applications of nanomaterials including carbon‐based (carbon nanotubes and graphene), typical 2D (topological insulators, transition metal dichalcogenides, black phosphorus, and MXenes), and metal‐based nanomaterials (gold, silver, copper, and metal oxides) are summarized. Major parameters of ultrafast lasers and features of each nanomaterial are presented simultaneously. Finally, the perspectives of nanomaterials for further development in ultrafast photonics are discussed.
