van der Waals Layered Tin Selenide as Highly Nonlinear Ultrafast Saturable Absorber

Abstract

Until now, III-V semiconductors have been primarily employed for commercial SAs because of their certified stabilities and performance. However, they suffer from limited operating bandwidth and expensive fabrication costs, which demand the development of new costeffective broadband SAs, ideally with more superior performance. To this end, a variety of materials have been investigated thus far, which include carbon nanotubes, [5][6][7][8][9][10][11][12] black phosphorus, [13][14][15][16][17][18] gold nanoparticles [19][20][21][22][23] and/or nanorods, [24] filled-skutterudites, [25] and topological insulators (TIs). [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] Recently, enormous research efforts have been dedicated to 2D materials such as graphene, [41][42][43][44][45][46][47][48] graphene oxide, [49] phosphorene, [50] and transition-metal dichalcogenides (TMDCs), as well as MXene that was first suggested by our recent study indi-

Low-dimensional materials as saturable absorbers for pulsed waveguide lasers

“…Several newly-developed 2D materials have shown its feasibility for pulsed lasing in fiber systems, such as TiS 2 , MXene, antimonene, and bismuthene [20,22,112,113]. Besides transition metal dichalcogenides (TMDCs), pulsed fiber lasers have also been demonstrated with layered transition-metal monochalcogenides (TMMCs) [23]. In addition, there is still plenty of room for pentagonal 2D materials and 2D V-V binary materials, which is recently emerged and predicted with superior properties by theoretical calculations [114][115][116][117].…”

“…Photonics 2 (2020) 031001 Z Li et al cannot fulfill, such as broadband operation, ultrafast recovery time, low cost, and better compatibility with compact devices such as fibers and waveguides. Recently, an increasing number of research efforts have been made to unfold the nonlinear optical properties as well as its corresponding applications of the emerging LD materials [14][15][16][17][18][19][20][21][22][23]. For semiconducting or semimetallic LD materials, the main mechanism for nonlinear saturable absorption is Pauli blocking.…”

Passively mode locked thulium and thulium/holmium doped fiber lasers using MXene Nb2C coated microfiber

“…Following the successful exfoliation of graphene and its first ultrafast application, other 2D materials including topological insulators (TIs) 41 , 56 – 59 , transition metal dichalcogenides (TMDs) 60 – 65 , metal chalcogenides 66 , antimonene 67 and MXenes 68 have been explored for their unique saturable absorption properties in ultrafast laser generation. Additionally, layered transition-metal monochalcogenides has also been used as SA for demonstrating pulsed lasers 69 . In the past few years, Jhon et al .…”

Watt-Level Continuous-Wave Mode-Locked Nd:YVO4 Laser With ReSe2 Saturable Absorber

“…Since the first report of graphene passively mode-locked laser in 2009 [10], a variety of graphene-like saturable absorbers have been exploited in passively mode-locking operation [11]. Various novel 2D materials inspired on graphene, such as black phosphorus (BP) [12,13], topological isolators (TIs) [14,15], topological Dirac semimetal (TDS) [16], MXene [17,18], Transition metal monochalcogenides (TMMCs) [19] and transition metal dichalcogenides (TMDs) have been demonstrated to be very promising saturable absorbers for ultrafast lasers as well [20][21][22][23][24][25][26][27][28]. These nanostructured nonlinear optical materials have witnessed a quite rapid development of stable and compact ultrafast sources.…”
