“…We noticed that among all the abovementioned research, DSR pulses temporally exhibit a uniform pulse train. Recently, Du et al numerically predicted the appearance of period doubling of DSR pulses in a fiber laser [30]. However, here we present experimental demonstration of period-doubling behaviors of DSR pulses.…”

We report an experimental demonstration of period doubling of dissipative soliton resonance (DSR) pulses in a fiber laser. DSR occurs in the close vicinity consisting of a set of parameters of a dissipative system, where the energy of the generated soliton increases without limit while the pulse peak power is clamped. Consequently, DSR pulses are immune to the appearance of period doubling, which is a threshold effect. However, period doubling of DSR pulses is experimentally demonstrated and numerically duplicated. The typical DSR feature, i.e., clamped pulse peak power and linear variation in pulse width with respect to the pump power change, is lost during the transition from period one to period doubling. However, the DSR performance reappears once the period doubling is fully developed. The breach and recurrence of DSR operation during pulse evolution results from the simultaneous change of multiple parameters because of the increasing pump power. In addition, DSR pulse narrowing with pump power increasing under the period-doubling state was experimentally observed.

optical computers, optical switches, pulsed laser generation, optical sensors, etc. As the fundamental information carrier of NLO, nonlinear optical materials have attracted great attention since the advent of the first laser and always been the research hotspot for material and optical scientists. In the last two decades, 2D materials, representative of the main including graphene, [1-3] topological insulators (TIs), [4-6] transition metal disulfides (TMDs) [7,8] and black phosphorus (BP), [9-11] have experienced an explosive growth because of the advantages of exotic optical, electronic, chemical, and mechanical properties that much differ from their bulk counterparts. Especially, the low dimensions and distinctive nonlinear optical properties make them strongly meet the ever-increasing demand and widely used in high efficiency, compactness, broadband optoelectronic and photonic devices, broadband all-optical modulator, optical frequency conversion, pulsed laser generation, surface plasmonic, and so on. [12-19] However, there are still some disadvantages for the current 2D materials. For example, the gapless band structure and relative low light absorption of graphene limit its extensive applications; [20,21] the band gap of TMDs (1.0-2.0 eV) indicates they cannot be available in mid-infrared wavelength range; [22,23] and easy oxidation is the biggest obstacle for practical applications of BP. [24,25] Therefore, it is still an urgent demand to explore promising novel 2D nonlinear optical materials. Recently, 2D MXenes have been extensively studied due to the unique optical and electronic properties. [26,27] MXene represents a large family of 2D transition metal carbides, carbonitrides, and nitrides, with the general formula of M n+1 X n T n (n = 1-3), where M represents a transition metal (e.g., Ti, Mo, Nb), X for either C and/or N, and T is the surface functional group (e.g.,-OH,-O, and-F). [28,29] Until now, more than 30 varieties of 2D MXenes have been synthesized and theoretically and experimentally studied, [30-34] revealing the outstanding features of metallic conductivity, large electric capacity, high mechanical strength, tunable band gap, high stability, high optical transparency, and large optical nonlinearities of MXenes. [35,36] Nb 2 C is a newly discovered 2D MXene with special band structure near the Fermi level, showing the great potential applications as electrode materials Niobium carbide (Nb 2 C), a newly developed 2D MXene material, has attracted much attention due to its outstanding electronic and optical properties. In this work, few-layer 2D Nb 2 C nanosheets are synthesized by magnetron sputtering deposition method. Z-scan measurements with pump source operating at 1.0 µm are performed to study the third-order nonlinear optical response, revealing excellent light modulation capabilities of 2D Nb 2 C. The effective nonlinear absorption coefficient (β eff ≈-10 5 cm GW-1) caused by saturable absorption effect is determined to be two orders of magnitude larger than that induced by reverse sat...

Intracavity energy rate in a soliton mode-locked fibre laser is derived by solving the Haus master equation. The influence of net gain, absorber response, saturation energy, nonlinearity and absorption are investigated on stable/unstable states. Intracavity modes include the zeroth, first and higher order solitons. Accordingly, chaotic regime as well as breather modes is recognized as a conventional intracavity state. However, tuning the control parameters also results in a reverse bifurcation and thus returning to a stable state. Accordingly, a chaos-based encryption/decryption system is proposed taking the advantage of using a single-side control process; both the encryption and decryption procedures can be achieved by one of the actions of increasing/decreasing the control parameters.
