“…However, the OSNR decreases for the SOA's current higher than 260 mA. The decrement of average OSNR at higher current is produced by the thermalization of the optical energy leading to a high temperature which causes fluctuation in their lasing line output power and operational wavelength [26]. The strong effect of the injection current can be vividly seen in Figures 10,11,and 12.…”

This paper presents the characteristics of C+L band semiconductor optical amplifier based multi-wavelength laser with the variation of output optical coupling ratios. The configuration was tested with different coupling ratios from 10% to 90%. Meanwhile, the semiconductor optical amplifier injection currents varied from 110 mA to 340 mA in a step of 10 mA. The optimum coupling ratios were observed at 30%, 40%, 50% and 60% since it produces the maximum number of lasing lines, optical signal-to-noise ratio and average peak power. These coupling ratios also correspond to the minimum drive current of the semiconductor optical amplifier that initiates the first lasing lines. At 60% of the coupling ratio and injection current of 280 mA, the multi-wavelength laser has the capability to generate up to 42 dominant lasing lines with average peak power from -21 dBm to -35 dBm and an average optical signal-to-noise ratio from 9 dB to 11 dB. Furthermore, the minimum semiconductor optical amplifier current of 110 mA was required to initiate the first lasing at 60% of the coupling ratio. The semiconductor optical amplifier can effectively and practically act as a multi-wavelength source, especially in optical sensing and communication.

“…Polarization controllers, although helpful in controlling the polarization of the laser output, and, thus, helping to obtain the mode-locked operation in multiple works, does add to the complexity of the fiber laser system and increase the system’s insertion loss. The limited range of adjustment of the polarization controller also limits its usefulness in certain applications [ 41 , 42 , 43 ]. The optical spectrum of the mode-locked pulse is depicted in Figure 13 , with the resolution of the OSA set at 0.02 nm.…”

We investigate the dynamics of high energy dual regime unidirectional Erbium-doped fiber laser in ring cavity, which is passively Q-switched and mode-locked through the use of an environmentally friendly graphene filament–chitin film-based saturable absorber. The graphene–chitin passive saturable absorber allows the option for different operating regimes of the laser by simple adjustment of the input pump power, yielding, simultaneously, highly stable and high energy Q-switched pulses at 82.08 nJ and 1.08 ps mode-locked pulses. The finding can have applications in a multitude of fields due to its versatility and the regime of operation that is on demand.

“…Self-injection feedback can reduce the noise of laser and improve the beam quality. [27] As shown in Figure 3(a), the arrow represents the propagation direction of some light. The light from the main cavity is incident from OC1, passes through OC2 and OC3, and then is incident again from the port of OC1 into the main cavity.…”

A single-longitudinal-mode (SLM) narrow-linewidth Brillouin erbium-doped fiber laser (BEFL) is proposed and demonstrated experimentally. The erbium-doped fiber (EDF) is employed to act as both the linear gain and Brillouin gain medium, which makes it easy to excite the stimulated Brillouin scattering (SBS) in the EDF by cooperating with the ring cavity structure. In order to realize stable SLM and narrow-linewidth laser output, the fiber saturable absorber (SA) and the self-injection feedback structure are added to BEFL for the first time, which can suppress the multimode phenomenon effectively and obtain a stable SLM status. The wavelength stability is less than 1.32 pm over 45 minutes and the linewidth is as narrow as 283 Hz.
