“…Chen et al first demonstrated the remarkable nonlinear optical properties of WS 2 –MoS 2 –WS 2 heterostructure in EDFL. 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 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. After investigating the characteristics of 2D materials thoroughly in nonlinear optics, their performances in fiber lasers are comprehensively summarized according to the types of materials. Finally, some developmental challenges, potential prospects, and future research directions are summarized and presented for such promising materials.

“…To obtain ultrashort pulses, the laser generally require a saturable absorber to achieve the mode locking mechanism. Various approaches have been developed since the early days of ultrafast lasers including physical light intensity absorbers such as semiconductor saturable absorption mirrors (SESAMs) [6], [7], carbon nanotubes [8], [9], graphene [10], [11], topological insulators [12], [13], black phosphorous [14], [15], and most recently transition-metal dichalcogenides (TMDs) [16], [17]. However, these physical absorbers either have bandwidth limitation or stability issues.…”

Abstract-We have systematically studied the 45° tilted fiber grating (45TFG) as a functional device for Erbium doped fiber laser (EDFL) mode locking. A number of 45TFGs with different polarization dependent loss (PDL) have been fabricated. Mode locked Erbium doped fiber laser using these devices have been characterized in terms of threshold, pulse duration, signal to noise ratio (SNR), and spectral width. Our results show that a 45TFG with higher PDL could achieve better laser results. By using a 45TFG with 24dB PDL, the mode locked laser has 8.1% conversion efficiency and a threshold of 200mW.

“…Recent reports have demonstrated that the energy band structures of the semiconducting TMDs show a unique transition from indirect to direct band gap as the thickness is reduced to monolayer [5][6][7]. These monolayer TMDs with direct band gap can offer exciting opportunities for potential applications in both electronic and optoelectronic devices [4, [8][9][10][11][12][13][14][15][16][17]. Among all TMD materials, WSe 2 has recently received huge interest due to their distinctive electro-optical properties and remarkable electronic characteristics [18][19][20][21][22][23][24].…”

Large-area and highly crystalline transition metal dichalcogenides (TMDs) films possess superior saturable absorption compared to the TMDs nanosheet counterparts, which make them more suitable as excellent saturable absorbers (SA) for ultrafast laser technology. Thus far, the nonlinear optical properties of large-scale WSe 2 and its applications in ultrafast photonics have not yet been fully investigated. In this work, the saturable absorption of chemical vapor deposition (CVD) grown WSe 2 films with large-scale and high quality are studied and the use of WSe 2 films as a broadband SA for passively mode-locked fiber lasers at both 1.5 and 2 μm ranges is demonstrated. To enhance the light-material interaction, largearea WSe 2 film is tightly transferred onto the side wall of a microfiber to form a hybrid structure, which realizes strong evanescent wave interaction between light and WSe 2 film. The integrated microfiber-WSe 2 device shows a large modulation depth of 54.5%. Using the large-area WSe 2 as a mode-locker, stable soliton mode-locked pulse generation is achieved and the pulse durations of 477 fs (at 1.5 μm) and 1.18 ps (at 2.0 μm) are demonstrated, which suggests that the large-area and highly crystalline WSe 2 films afford an excellent broadband SA for ultrafast photonic applications.
