“…The bandwidth demand of optical fiber communication continues to grow; this has caused insufficient bandwidth and channel capacity when only the C-band (1530-1565 nm) is used. A great deal of research is focused on the nearby L-band (1565-1625 nm) to expand the available bandwidth [1][2][3]. As the wavelength range of typical erbium-doped fiber (EDF) lasers can only cover the C-and L-bands, less research effort is devoted to the S-band (1460-1530 nm).…”

An all-fiber S-band mode-locked Er-doped fiber ring laser operated at 1503 nm is experimentally demonstrated by utilizing the polarization additive-pulse mode-locking (P-APM) mechanism. To the best of our knowledge, it is the first P-APM mode-locked fiber laser operating in the S-band. The gain medium is an S-band Er-doped fiber amplifier (EDFA) composed of two Er-doped fiber stages with the technique of depressed-cladding to cut off the fundamental mode. Stable single-pulse operation is achieved within the available pump power range. Besides, characterization of the S-band EDFA module, such as the wavelength dependences of the gain and noise figure, the slope efficiency, as well as the dependence of the pump power on the gain for different input powers is performed. In addition, analysis of the proposed S-band mode-locked fiber laser, such as the pump power dependence of the pulse-width and optical bandwidth, and pulse-width compression is also provided.

“…To obtain a wide tunability in fiber laser scheme, using the hybrid EDFA and semiconductor optical amplifier (SOA), Bi 2 O 3 (Bi) based EDF and high gain EDF inside fiber cavity [24][25][26][27] have been demonstrated and discussed. Furthermore, to provide a flattened output power range in EDF based laser scheme, several methods have also been studied, such as applying another optical filter, adjusting a pump power of EDFA dynamically, and using hybrid optical amplifiers [28][29][30].…”

In this study, we present and experimentally demonstrate an erbium-doped fiber (EDF) quad-fiber-ring (QFR) laser with selectable and flat single-longitudinal-mode (SLM) wavelength output. The designed QFR scheme not only can suppress dense multi-mode oscillation, but also can broaden and flatten the output wavelength covering C- and part of L-bands over a bandwidth from 1519.0 to 1579.0 nm when using a C-band EDF as gain medium. Additionally, the output power, optical signal to signal ratio (OSNR), linewidth, stability and tunability of the proposed EDF laser are also discussed.

“…Generally, to accomplish a wavelength-tunable output with single longitudinal mode (SLM), the several wavelength selective elements (optical filters) and laser architectures have been used inside ring cavity. The proposed fiber lasers could be designed in linear or ring architectures [16,17]. Besides, the fiber Fabry-Perot filter (FFPF), tunable bandpass filter (TBF), and fiber Bragg grating (FBG) could be utilized inside the fiber ring cavity to select different wavelength lasing.…”

“…Besides, the fiber Fabry-Perot filter (FFPF), tunable bandpass filter (TBF), and fiber Bragg grating (FBG) could be utilized inside the fiber ring cavity to select different wavelength lasing. In fact, owing to the limited gain amplification of the amplifiers, the output power would drop rapidly on both sides of their operating bandwidth [16][17][18].…”

In this chapter, there are three sections to demonstrate the reflective semiconductor optical amplifier (RSOA)-based fiber laser architectures for multiwavelength and wavelength-tunable operations. In the first section, we introduce an L-band multiwavelength laser by utilizing a C-band RSOA with a linear cavity, which is produced by a polarization controller (PC), an optical coupler (OCP), and a reflected fiber mirror (RFM). In the proposed RSOA laser scheme, two to seven wavelengths could be lased and created simultaneously in the L-band range, while the RSOA operates at various bias currents. In the second section, we demonstrate a multiwavelength laser source by utilizing a Cband RSOA with dual-ring fiber cavity. In the measurement, the laser cavity is constructed by an RSOA, a 1×2 OCP, a 2×2 OCP, and a PC, respectively. Thus, 13-18 wavelengths around L-band could be produced simultaneously, as the bias current of C-band RSOA is driven at 30-70 mA.
