“…Consequently, interference occurred from port 2 to the FBG, and a standing wave was established. [53,54] A polarization controller was embedded between the SA and FBG. Thus, the reflected beam exhibited monodirectional transmission due to the circulator and propagated from port 2 to port 3.…”

As a new IV-V group semiconductor, germanium-diarsenide (GeAs 2 ) compounds have attracted considerable attention due to their outstanding optical and electrical properties, thickness-dependent bandgap, in-plane anisotropy, and excellent optical absorption. However, the potential of GeAs 2 in the field of ultrafast and ultranarrow fiber laser has not been studied. In this article, a high-quality GeAs 2 nanosheets saturable absorber (SA) is successfully prepared by liquid-phase exfoliation. The nonlinear optical characteristics of GeAs 2 nanosheets have been investigated based on a balanced twin-detector measurement system. The modulation depth, nonsaturable loss, and saturation intensity are measured to be 5.2%, 24%, and 1.23 GW cm −2 , respectively. GeAs 2 has been successfully applied as an SA in an ultrafast and singlefrequency fiber laser. A stable mode-locked laser pulses operation with a duration as short as 371 fs and a repetition rate of 8.19 MHz at a wavelength of 1560 nm is achieved. Moreover, ultranarrow fiber lasers with a high signalto-noise ratio of 80 dB and a linewidth of ≈678 Hz are obtained. The findings validate that 2D GeAs 2 can be used as an SA and has promising applications in ultrafast and ultranarrow photonics.

“…It is equivalent to an instantaneous grating with an ultranarrow bandwidth. [53,54,58] As a result, the SA can contribute to suppressing the competition between various frequencies. [59] In addition, the loop cavity is capable of selecting the laser frequency according to the effect of the travelling wave cavity.…”

“…The unsaturated gain coefficient g us of the active HNL-PCF is set to 40 dB/m, thereby being capable of resulting in the overall energy gain at the fiber end of ∼10 dB along with the other given parameters. We note that the unsaturated gain coefficient corresponds to a core absorption rate of 178 dB/m at 976 nm, which is readily achievable with current fiber fabrication techniques [28]. The effective saturation energy per single-pulse denoted as E sat /N * is set to 3 nJ, which is a typical value for a Yb-doped fiber amplifier with a MHz-level repetition rate [9].…”

We numerically study supercontinuum (SC) generation (SCG) in a rare-earth-doped highly nonlinear photonic crystal fiber (HNL-PCF) with anomalous dispersion (AD) in the sub-picosecond pulse regime. We develop a semi-classical numerical model based on the generalized Ginzburg-Landau equation in order to take account of ultrafast interactions between gain ions and ultra-broadband SC radiation encompassing sub-100femtosecond solitons. Based on the numerical model, we analyze SCG characteristics of an active HNL-PCF in comparison with a passive-type counterpart, unveiling novel optical gain effects in a highly nonlinear optical fiber with AD. We rigorously investigate gain-induced soliton dynamics, such as soliton-cascadelike behaviors, soliton-quasi-soliton collisions, and phase-matched dispersive wave generation, which eventually contributes to enhancement of energy scaling of SC radiation without incurring considerable degradation of its spectral flatness. We also verify that such superior performance characteristics of an active HNL-PCF make it suitable for the use as a boost amplifier for SC radiation. We think that the findings from this study will incite other subsequent studies on unveiling detailed nonlinear pulse dynamics in various gain-embedded nonlinear optical media.

“…Despite these merits, the long cavity length in SFFLs may cause multi-longitudinal-mode (MLM) oscillation, deleterious to laser performance. To mitigate this, a number of ultra-narrowband filters have been introduced in the ring cavity laser, such as Fabry-Perot cavity-based filters [13], sub-ring resonators based on cursor effect [14], and ultra-narrowband induced grating with a saturable absorber (SA) based on twodimensional materials and unpumped Yb-doped fibers [15,18,19]. Among them, the SFFLs with a section of unpumped Ybdoped fiber can not only offer an all-fiber structure but also a low insertion loss.…”
