The tunable bandgap from 0.3 eV to 2 eV of black phosphorus (BP) makes it to fill the gap in graphene. When studying the properties of BP more comprehensive, scientists have discovered that many two-dimensional materials, such as tellurene, antimonene, bismuthene, indium selenide and tin sulfide, have similar structures and properties to black phosphorus thus called black phosphorus analogs. In this review, we briefly introduce preparation methods of black phosphorus and its analogs, with emphasis on the method of mechanical exfoliation (ME), liquid phase exfoliation (LPE) and chemical vapor deposition (CVD). And their characterization and properties according to their classification of single-element materials and multi-element materials are described. We focus on the performance of passively mode-locked fiber lasers using BP and its analogs as saturable absorbers (SA) and demonstrated this part through classification of working wavelength. Finally, we introduce the application of BP and its analogs, and discuss their future research prospects.

“…By employing a hybrid of SIMF-GIMF SAs, stable mode-locking operations were achieved in a TDFL [17] and erbium-doped fiber laser [18], respectively. Other combinations of SMF-GIMF-SMF SAs, such as offset-spliced GIMF [19] and tapered GIMF [20] are also reported. Until now, a variety of MMF-based SAs have been developed and applied to ultrafast fiber lasers in wide wavelength regions covering 1, 1.55 and 2 µm [21][22][23][24].…”

In this work, an all-fiber saturable absorber (SA) based on nonlinear multimode interference in a short few-mode fiber (FMF) was proposed. Saturable absorption in this all-fiber device was demonstrated with an absorption modulation depth and a saturation fluence of 14.3% and 55.6 μJ cm−2, respectively. A stable mode-locking operation was observed in a thulium-doped passively mode-locked fiber laser using the FMF-based FMF SA. Ultrafast pulses were generated at 1911 nm with a pulse width of 1.96 ps and a 15.69 MHz repetition rate, respectively. The output average power was 2.8 mW, corresponding to a pulse energy of 178 pJ, which was significantly improved compared to graded-index multimode fiber-based SA. The experimental results demonstrate that FMF SA has great potential in eye-safe ultrafast photonics.

“…In all-normal-dispersion (1 μm waveband) [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ] and the anomalous-dispersion domain (1.5 μm, 2 μm) [ 29 , 30 , 31 , 32 , 33 , 34 ], the lasers based on NL-MMI as SA have been studied by many scholars. In 2018, Tegin et al used NL-MMI mechanism for the first time to realize mode-locking operation in the 1 μm region [ 19 ].…”

“…In order to improve the modulation depth of SA and the output performance of ultrashort mode-locked fiber lasers, many mode-locking structures have been proposed in recent years. For example, Dong proposed the use of an offset-spliced GIMFs (OS-GIMFs) structure as SA in 2019 [ 20 ], and S Thulasi proposed the use of a no-core fiber (NCF)-GIMF structure as SA in 2020 [ 21 ]. At the same time, Wang et al used the SIMF-GIMF structure as SA and successfully output the mode-locked pulse in erbium-doped mode-locked laser for the first time in 2017 [ 29 ].…”

Dispersion management plays an important role in improving the output performance of a mode-locked fiber laser. Therefore, dispersion management is carried out by introducing the grating pair in our experiment. Through adjusting the distance between the grating pair, mode-locked pulses corresponding to different dispersion regimes can be realized, which typically range from soliton state in the anomalous dispersion regime to the dissipative soliton format in the normal dispersion regime. Furthermore, tunable spectrum distribution can be achieved by adjusting two intra-cavity polarization controllers. The proposed dispersion management method complements mode-locking techniques based on nonlinear multimode interference (NL-MMI). The laser can operate with self-start mode locking stably and is useful for practice applications.
