Blue-Shifted Rogue Waves Generation in Normal Dispersion Fiber Laser

Abstract

In the presence of noise in normal dispersion fiber mode-locked lasers, "dissipative resonance" disappears, which leads to instability of spectral broadening and makes the asymptotic accumulation of energy impossible. We experimentally generate dissipative soliton molecules-like spectral peaks and rogue waves in the frequency domain in a self-mode-locked fiber laser. Due to noise in the initial triangular-shaped mode locked wave, these molecules are arranged in the form of lobes on the longer wavelength side, thus forming three virtual groups of soliton molecules. Further dissipative accumulation of power in the mode-locked wave ultimately leads to the formation of a blue-shifted group of three rogue waves, due to the effective fusion of adjacent soliton molecules. This is the first report of an experimental observation of blue-shifted and three rogue waves in a single experiment. The results have far reaching implications for experimentation with soliton collisions, optical rogue waves, and understanding of hydrodynamics.Index Terms-Passive mode-lock fiber lasers, normal dispersion, instability of dissipative soliton resonance, bound solitons, supercontinuum, rogue waves.

Supersymmetrical bounding of asymmetric states and quantum phase transitions by anti-crossing of symmetric states

“…3, which is identical to that reported in refs 39, 40, 41. The ring cavity consisted of four types of fibres having different normal dispersion values, zero dispersion wavelengths and core diameters.…”

“…In addition, changes in the comb structure were observed, presenting a different feature compared to previous studies in field of soliton combs. Therefore, in addition to the soliton combs of different spacing, we also observed soliton molecules of different structures and compound (multicomponent) rogue waves394041. The properties of the solitons are discussed in detail in ref.…”

“…The properties of the solitons are discussed in detail in ref. 41. Using the same experimental setup, however, at different birefringence and polarization conditions, and at pump power of 230 mW, we achieved soliton combs with 0.54 nm (~170 GHz) and 0.63 (~199 GHz) spacing with the particular structures shown in Fig.…”

Recent progress on optical rogue waves in fiber lasers: status, challenges, and perspectives

“…80 Since then, the study of dissipative RWs in fiber lasers has been rapidly developing. [53][54][55]79,[81][82][83][84][85][86][87][88][89][90][91][92][93][94][95][96][97] RWs in fiber lasers can be categorized by pulse duration as three types, 94 namely slow RWs, fast RWs, and ultrafast RWs. These RWs are generated by different mechanisms.…”

Rogue waves generation via nonlinear soliton collision in multiple-soliton state of a mode-locked fiber laser

“…Mode-locked fiber lasers which have abundant physical effects including nonlinearity, dispersion, gain and loss, are excellent platforms for nonlinear sciences investigation such as RWs. Indeed, recently, RWs were observed in mode-locked fiber lasers under different mode-locking states [5][6][7][8][9][10][11][12]. As well known, there are several mode-locking states in fiber lasers.…”
