“…Many researchers have been attracted by noble metal nano-materials, such as gold, silver, due to the strong non-linear optical (NLO) effects which caused by their surface plasmon resonances (SPR) (Oh et al, 2011; Tsutsui et al, 2011; Huang et al, 2014; Komarov et al, 2015; Fan and Zhang, 2016; Yang et al, 2018). These effects enable noble metal nano-materials get many potential applications in synthesize NLO devices, such as optical detectors, optical sensors, and optical absorbers (Jain et al, 2007; Zijlstra et al, 2009).…”

Gold nanorods (GNRs) has been investigated in the field of chemistry, optoelectronics, and medicine for their tenability, compatibility, electromagnetics, and excellent photonics properties. Especially, GNRs, used to generate ultrashort pulse, have been studied recently. However, multiple pulses evolution based on GNRs needs to be further explored. In this article, GNRs are synthesized by seed-mediated growth method, characterized systematically and been chosen as saturable absorber (SA) to apply in ultrafast photonics. The GNRs SA presents a saturable intensity of 266 MW/cm2, modulation depth of 0.6%, and non-saturable loss of 51%. Furthermore, a passively mode-locked erbium-doped fiber laser based on GNRs SA with femtosecond pulse is demonstrated. Thanks to the excellent properties of GNRs, by adjusting the cavity polarization direction with the proposed GNRs SA, soliton molecules operation with spectrum modulation period of 3.3 nm and pulse modulation interval of 2.238 ps is directly obtained. For the most important, 9th-order harmonic soliton molecules have been generated in the laser cavity for the first time. It is demonstrated that GNRs can be a novel type of non-linear optical (NLO) device and have potential applications in the field of ultrafast photonics.

“…HML is typically achieved by increasing the intracavity power, which can contribute unbalanced nonlinear effects, finally causing the circulating pulse to break up into multiple pulses [8]. Depending on the physical effects governing the interaction between the asformed pulses, these can self-organize into two or more closely (temporally) spaced pulses [9,10]. For example, cross-phase modulation between pulses can lead to the formation of a soliton pair, termed bound states (BS) or soliton molecules, with a temporal spacing (Δτ) limited to several times of their pulse duration [11].…”

We report bound states of solitons from a harmonic mode-locked fiber laser based on a solution-processed graphene saturable absorber. Stable soliton pairs, 26.2 ps apart, are generated with 720 fs duration. By simply increasing the pump power, the laser can also generate harmonic mode-locking with harmonics up to the 26th order (409.6 MHz repetition rate). This is a simple, low-cost, all-fiber, versatile multifunction ultrafast laser that could be used for many applications.

“…Although the dissipative solitons can tolerate strong nonlinearity, higher pump level leads to the generation of multiple solitons. Generally, various soliton operations have been observed, such as vector solitons [29], multi-pulsing [30], and harmonic mode locking [31], bound-state solitons [32]. Two bound solitary pulses, so-called bound states or soliton molecules, have attracted a lot of interest because of their potential applications in optical communications for coding and transmission of information in higher-level modulation formats, increasing the capacity of communication channels beyond binary coding limits [33].…”

Numerical simulations are conducted on dynamic evolution of the soliton molecules in an all-normal dispersion fiber laser. Peak-to-peak (PP) separation can be controlled by adjusting gain saturation energy (E sat ). Moreover, with the increase of E sat , the soliton molecules do not split into three bound states directly while it shows to avoid generating three bound states through a series of adaptive adjustments, thus we conclude that the soliton molecules have high nonlinearity tolerance. After adaptive adjustments each soliton has the same physical properties and a fixed PP separation to keep propagation. According to this paper, we can deeply understand the dynamic evolution of the soliton molecules.
