Investigations into semiconductor nanomaterials from both an academic and industrial point of view are of great significance. Selenium (Se) nanostructures, as narrow bandgap semiconductors, have a variety of potential applications in the fabrication of many high-performance devices. The past decades have witnessed rapid development in new strategies for synthesizing Se nanostructures with controlled sizes, shapes, and structures, whose diverse structure-dependent nature enables functional Se nanomaterials to have great potentials for modern applications. This review focuses on the synthesis and morphology control of intriguing Se nanostructures, the latest progress in understanding the fundamental properties of Se nanostructures, and the recent advances in high-performance Se nanomaterial-based devices for diverse applications. Finally, the challenges and future opportunities for Se nanostructures and Se-related devices are also discussed.

“…B. Liu first reported a fiber laser that was passively mode-locked by filling graphene oxide (GO) solution into the photonic crystal fiber (PCF) as a SA [133]. As shown in Figure 7(d) [132], the prepared material solution can be filled into the PCF with highpressure injection method. Then, the solution-filled PCF was oven dried in order to remove the solvent and splice with the single-mode fiber [134].…”

Abstract Due to the unique properties of two-dimensional (2D) materials, much attention has been paid to the exploration and application of 2D materials. In this review, we focus on the application of 2D materials in mode-locked fiber lasers. We summarize the synthesis methods for 2D materials, fiber integration with 2D materials and 2D materials based saturable absorbers. We discuss the performance of the diverse mode-locked fiber lasers in the typical operating wavelength such as 1, 1.5, 2 and 3 μm. Finally, a summary and outlook of the further applications of the new materials in mode-locked fiber lasers are presented.

“…Two-dimensional materials (2DMs) have emerged as promising SAs with a number of favorable properties for laser development [29,30], such as broadband operation [31,32], controllable modulation depth [33], and ultrafast recovery time [34,35]. In addition, they can be solution processed by means of wet chemistry [36], making them easy to fabricate and integrate into all-fiber configurations.…”

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.
