Graphene and the following derivative 2D materials have been demonstrated to exhibit rich distinct optoelectronic properties, such as broadband optical response, strong and tunable light–mater interactions, and fast relaxations in the flexible nanoscale. Combining with optical platforms like fibers, waveguides, grating, and resonators, these materials has spurred a variety of active and passive applications recently. Herein, the optical and electrical properties of graphene, transition metal dichalcogenides, black phosphorus, MXene, and their derivative van der Waals heterostructures are comprehensively reviewed, followed by the design and fabrication of these 2D material‐based optical structures in implementation. Next, distinct devices, ranging from lasers to light emitters, frequency convertors, modulators, detectors, plasmonic generators, and sensors, are introduced. Finally, the state‐of‐art investigation progress of 2D material‐based optoelectronics offers a promising way to realize new conceptual and high‐performance applications for information science and nanotechnology. The outlook on the development trends and important research directions are also put forward.

“…The pulse duration as short as 296 fs and average power as high as 25 mW further illustrated the superiority of WS 2 –MoS 2 –WS 2 heterostructure in optical nonlinearity 351. Soon afterward, Liu et al combined heterojunction with tapered fiber to obtain a MoS 2 –WS 2 SA with better performance 352. The MLFL based on prepared MoS 2 –WS 2 SA owned the SNR of 91.2 dB and power jitter of 0.123, which indicated the remarkable stability of the system.…”

The explosive success of graphene opens a new era of ultrathin 2D materials. It has been realized that the van der Waals layered materials with atomic and less atomic thickness can not only exist stably, but also exhibit unique and technically useful properties including small size effect, surface effect, macro quantum tunnel effect, and quantum effect. With the extensive research and revealing of the basic optical properties and new photophysical properties of 2D materials, a series of potential applications in optical devices have been continuously demonstrated and realized, which immediately roused an upsurge of study in the academic circle. Therefore, the application of 2D materials as broadband, efficient, convenient, and versatile saturable absorbers in ultrafast lasers is a potential and promising field. Herein, the main preparation methods of 2D materials are reviewed and technical guidelines for identifying and characterizing layered 2D materials are provided.

“…Transition-metal dichalcogenides (TMDs) possess unique photoelectric properties that vary with thickness. They not only exhibit ultra-wideband absorption characteristics due to defective states but also have outstanding performance in realizing ultrafast lasers [43][44][45]. Similarly, topological insulators (TIs) and black phosphorous (BP) have recently got breakthroughs in applications of photonics and photoelectronics in the near-infrared band [46][47][48][49].…”

Yttrium oxide (Y 2 O 3 ) has been widely used in metal-reinforced composites, microelectronics, waveguide lasers, and high-temperature protective coatings because of its good physical and photoelectric properties. However, few studies have been done on the nonlinear optical applications of Y 2 O 3 as saturable absorbers (SAs) in fiber lasers so far. Here, a passively Q-switched nearinfrared fiber laser using Y 2 O 3 as a Q-switching device is demonstrated. The optical nonlinear properties of the Y 2 O 3 SA prepared by the magnetron sputtering method were measured by the twin-detector measurement technique, and the modulation depth of the proposed Y 2 O 3 SA was found to be 46.43%. The achieved Q-switched laser delivers an average output power of 26 mW at 1530 nm with a pulse duration of 592.7 ns. To the best of our knowledge, this is the first report on the optical nonlinearity of Y 2 O 3 as a Q-switcher for the near-infrared fiber laser, which may deepen the understanding of the optical nonlinear properties of Y 2 O 3 and make inroads into the potential market of optical modulation and optoelectronic devices.
