“…Since the initial report by Bao et al [37], mode-locked fiber lasers based on graphene saturable absorbers have attracted much attention due to their outstanding properties including ultrafast recovery time, wide range wavelength tunability, low saturation power, large modulation depth, and high damage threshold [38][39][40]. Thus, graphene based saturable absorber is a promising candidate to realize hybrid mode locking.…”

Mode locked pulse generation has been reported using both active and passive mode locking schemes. Active mode locking technique has been proven to be an effective way to generate high-repetition-rate pulses by incorporating a modulator inside the laser cavity. Compared to actively mode locked lasers, passively mode locked lasers can generate pulse train at ultrashort pulse width but with relatively lower repetition rate. Thus, it is a brilliant idea to build a hybrid mode locked system combining both active and passive mode lockers. In this review, several hybrid mode locked fiber ring laser systems are discussed and summarized. Hybrid mode locking is a promising method to generate high speed ultrashort optical pulses for fiber-optic telecommunication system.

“…There are several methods of preparing graphene suitable for mode-locking: 1) epitaxial growth by chemical vapor deposition (CVD) on various substrates (mostly Cu and Ni) [36], 2) direct exfoliation of natural graphite by ultrasonification it in various organic solvents e.g. dimethyloformamide (DMF) [37], 3) mechanical exfoliation of graphene from bulk graphite [38][39][40][41]. An exemplary setup of an Erdoped fiber laser mode-locked by CVD-graphene saturable absorber is shown in Fig.…”

Abstract. For the last decade a very attractive field of laser physics, namely the optical frequency comb technique, has been intensively developed. Fiber lasers play particular role in that area. The motivation of their development is obtaining broadband comb systems with well-defined and stable mods (comb teeth). This paper presents a basic overview devoted to the fiber-based optical frequency combs.

“…Single-wall carbon nanotubes (SWCNTs) have attracted much attention in the field of optical communications in recent years because of their ultrafast nonlinear optical properties in the near-infrared region arising from the saturation of excitonic transitions, [1][2][3][4] their interesting electronic and optical properties, and several applications in photonics, which include nanometer-scale devices for light generation, photodetection, photovoltaic applications, and application as saturable absorbers (SAs). 5,6 Recent developments in fiber lasers have led to a renewed interest in SAs.…”

Abstract. We investigate the generation of a chirped pulse in a single-mode, ring-cavity, erbium-doped fiber laser employing carbon nanotubes (CNTs) as a saturable absorber (SA). The pulse propagation is simulated using analytical methods to understand and quantify the role of multiple SA properties, particularly in the propagation dynamics of the laser pulse. The soliton solution is obtained on the basis of nonlinear effects, such as gain dispersion, second anomalous group-velocity dispersion, self-phase modulation, and two-photon absorption for a generalized nonlinear Schrodinger equation. The influences of the SA parameter in the range from 0.1 to 0.4 on the chirp, power, and width of the soliton are calculated. A stable, passively mode-locked fiber laser using CNTs as an SA is modeled. In addition, the power, width, chirp, and phase of the soliton pulses can be tuned by choosing suitable SA parameters.
