“…The net dispersion of the Er 3+ -doped fiber laser is calculated to be −0.25 ps 2 . The negative dispersion value close to zero is suitable for generating BDSs. − The output pulse’s property is examined and analyzed using a 3 GHz photodetector, an optical power meter (Thorlabs), a digital oscilloscope (Tektronix MDO3102), and a spectrum analyzer (Anrisu MS9710C).…”

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.

“…Passively mode-locked fiber laser cavities provide an excellent platform for investigating the complex dynamics of nonlinear optics, such as harmonic mode-locking, soliton and bound state [1][2][3][4]. Due to a multiple interplay among dispersion, nonlinearity, loss, gain, spectral filtering and so on, some special solutions are obtained, including dark pulse, bright pulse, and bright-dark pair [5][6][7]. A dark soliton was experimentally observed in 1987 [8], and since then different kinds of dark pulses have been demonstrated [5,6].…”

The nonlinear Schrödinger equation with inhomogeneous diffraction and nonlinearity in the presence of PT-symmetric potentials is investigated, and an analytical bright 2D spatial soliton is obtained. The positive and negative signs in the parameters of the PT-symmetric potentials lead to four permutation and combination cases. The dynamical evolutions of the spatial soliton in the periodic modulated system and the diffraction decreasing waveguide are discussed. Dynamical characteristics of the form factors for the spatial soliton including the amplitude, width and phase are studied. Moreover, two kinds of nonlinear PT phase change are presented. These results may provide alternative methods in potential applications of synthetic PT-symmetric systems.
