“…Glycerin is an organic liquid with a conjugated chain structure, composed of carbon hydrogen bonds (C-H), carbon oxygen bonds (C-O), oxygen-hydrogen bonds (O-H), and carbon-carbon bonds (C-C) [150]. This material has a broadband absorption ranging from 1500 to 2000 nm owing to the stretching vibration and flexural vibration of different covalent bonds [150]. Glycerin shows the advantages of less volatility and lenient packaging challenges to keep the mode-locking abilities to typical alcohol [151].…”

“…Compared with other materials, Ayph has a stronger delocalized π electronic system as an organic substance, so the electron transmission ability is stronger, and the detection of its optical nonlinear transmittance proves that it has a suitable modulation depth. In addition, a summary of the output characteristics of fiber lasers based on Ayph and other SAs is shown in Table . ,,,,− The mode-locked output characteristics in erbium-doped fiber lasers also have good overall performance, indicating that it can cover important communication frequency bands and has a wide range of applications. Through further optimization of the structure, we will obtain better parameters.…”

“…This leads to scientists to search for many different SAs that are easier to prepare and have excellent properties. In previous work, ultrafast lasers based on some organic materials have been successfully realized, which provide theoretical support and possibility of using organic saturable absorbers for the ultrafast photonics application. − However, hydrazone organics have not been used in a pulsed laser, which provides a new idea for pulsed laser research, and the characteristics of hydrazone organics need to be further studied.…”

The hydrazone organics have obvious third-order nonlinear optical properties because of the existence of the delocalized π-electrons and the strong coupling between electrons with geometric structure. Compared with traditional inorganic materials, hyrazone materials have the advantages of fast response time, low dielectric constant, convenient preparation, and strong delocalization electronic system. However, the strength of this material in nonlinear optics and ultrafast photonics is rarely involved. In this article, we studied the optical energy gap through the density functional theory (DFT) method to verify the nonlinear absorption characteristics of hydrazone compound 1-(anthracen-9-ylmethylene)-2-(perfluorophenyl)hydrazine (Ayph). The nonlinear transmission characteristics of Ayph are studied with high modulation depth of ∼7.46% and saturation absorption intensity of ∼49.37 MW·cm–2. Most importantly, by adding Ayph saturable absorber to the Er-doped fiber laser, we are able to generate ultrashort pulses with very stable operation at a central wavelength of 1563.9 nm first. The preparation and characterization of Ayph and other characteristics of traditional soliton pulse are also discussed. It has been proved that Ayph is a promising material for ultrafast broadband nonlinear optics for the first time to our knowledge. Considering the material’s rich characteristics and structural controllability, these studies lay the foundation for multifeature photonics.

“…We believe that pulse broadening is mainly caused by chirp, which is similar to the previous reports. 54,55 For different pump power values, the pulse time interval is unchanged with a time interval of 0.159 μs, corresponding to the time of light propagating in the cavity for one circle.…”

As a group IV graphene-like material, germanene has fast carrier relaxation time and excellent nonlinear saturable absorption properties, which make it have a broad application prospect in the field of optics. However, in the field of laser applications, it has not been sufficiently studied. In this study, the energy band and optical property calculations of germanene with two structural defects were performed based on the density functional theory. The germanene nanosheet prepared by a liquidphase exfoliation method was systematically characterized and analyzed. High-quality germanene-saturable absorbers were selected for application in erbium-doped fiber lasers. By adjusting the device, a bright−dark soliton with a fundamental frequency of 6.28 MHz and a single-pulse energy of 2.58 nJ was obtained. Meanwhile, the dark−dark−bright, dark−bright−dark, and dark−bright−bright solitons were also experimentally observed and characterized. The study shows that germanene nanosheets have excellent nonlinear saturable absorption properties for bright−dark soliton's modulation. It also provides theoretical and experimental bases for the application of germanene in the field of ultrafast lasers.
