“…EDF lasers account for about half of the tunable lasers demonstrated in table 1, indicating the wide application of the 1500 nm laser and the significance of research on it. In addition to EDF, multiple cases of 1.5 μm tunable lasers with thulium-doped fluoride fiber as the gain fiber have been reported [63][64][65][66]. Besides, Peng et al reported a 1.5 μm tunable laser with bismuth-erbium doped fiber as the gain fiber [67].…”

“…A MoWS 2 -based EDF laser was designed, whose wavelength ranges were from 1466 to 1502 nm and 1473 to 1525 nm for EDF spooling diameters of 5.5 and 6.5 cm respectively[75]. On the generation of EDF tunable lasers, Ahmad and his team also made outstanding contributions to this field by testing a series of TMDs from the years 2018 to 2021, including MoS 2 , MoTe 2 , WSSe, In 2 Se 3 , and ZrSe 2[63,67,[76][77][78]. In 2021, Kim et al reported a GObased EDF laser with a tuning range of 1564-1604 nm.…”

Nanomaterials are widely used in the fields of sensors, optoelectronics, biophotonics and ultrafast photonics due to their excellent mechanical, thermal, optical, electrical and magnetic properties. Particularly, owing to their nonlinear optical properties, fast response time and broadband operation, nanomaterials are ideal saturable absorption materials in ultrafast photonics, which contribute to the improvement of laser performance. Therefore, nanomaterials are of great importance to applications in wavelength-tunable broadband pulsed lasers. Herein, we review the integration and applications of nanomaterials in wavelength-tunable broadband ultrafast photonics. Firstly, the two integration methods, which are direct coupling and evanescent field coupling, and their characteristics are introduced. Secondly, the applications of nanomaterials in wavelength-tunable broadband lasers are summarized. Finally, the development of nanomaterials and broadband tunable lasers is reviewed and discussed.

“…Besides graphene, transition metal dichalcogenides (TMDs) are also categorized as one of the 2D materials. TMD is a combination of Group 4-7 transition metals (M) and chalcogen (X) in the form of MX 2 [10], such as zirconium diselenide (ZrSe 2 ) [11], titanium diselenide (TiSe 2 ) [12], molybdenum telluride (MoTe 2 ) [13], nickel telluride (NiTe 2 ) [14], platinum diselenide (PtSe 2 ) [15], and zirconium disulfide (ZrS 2 ) [16]. Since the thickness of TMD affects its optoelectronics properties [13], meticulous fabrication procedures are required, which become the limiting factor for tailoring their properties.…”

We demonstrate the utilization of iron oxide (Fe2O3) as light-absorbing material in an erbium-doped fiber laser (EDFL) for the generation of Q-switched pulses. A sandwich-type saturable absorber (SA) with Fe2O3 nanoparticles between fiber ferrules is proposed. A fiber ferrule tip is tapped onto a cap of index-matching gel, which is then dipped into Fe2O3 nanoparticle powder to allow its deposition through the adhesion effect. By incorporating Fe2O3–SA in an EDFL, self-started and stable Q-switched pulses are attained at a threshold power of 50.1 mW. The pulse repetition rate is tunable from 9.92 kHz to 22.47 kHz, whereas the pulse duration reduces from 38.4 µs to 13.8 µs with the pump power increment. The maximum pulse energy achieved is 36.9 nJ. This work offers a simple integration method of Fe2O3 nanoparticles as potential SAs for the generation of Q-switched pulses.

“…On the one hand, multi-wavelength EDFL has more laser lines, high output power, high stability and wide tuning range [2]. On the other hand, its compact structure, better cost effectiveness and low insertion loss are impressive [3]. In addition, in practical application, compared with fixed-wavelength fiber lasers, multi-wavelength EDFL have greater value because of variable output wavelengths with adjustable spacing.…”

Tunable and Switchable Multi-Wavelength Erbium-Doped Fiber Laser Based on Composite Structure Filter

et al. 2022

View full text Add to dashboard Cite

A multi-wavelength erbium-doped fiber laser (MW-EDFL) with wide tuning range, switching and adjustable wavelength interval is designed and tested, which is based on a composite filter. The filter consists of a tapered microfiber coupler loop (TMCL) with a nested single mode fiber (SMF)-two mode fiber (TMF)-SMF (STS) structure, which has a comb spectrum with obvious envelope and uniform fluctuation. Our experimental and theoretical results show that the laser can output thirteen wavelengths, when the angles of two polarization controllers (PCs) in the TMCL are accurately set. Moreover, by adjusting the PCs, the tuning range of single- to sextuple-wavelength can reach about 40 nm. Six non-adjacent multi-wavelength outputs can be observed in some specific polarization states. The maximum side-mode suppression ratio (SMSR) of the output laser is 40.6 dB. Compared with other multi-wavelength EDFL, the output characteristics of the laser, such as the adjustability and flexibility of wavelength spacing and the switch-ability of wavelength number, have been improved.
