“…Finally, RDFB-FL schemes allow combining the traditionally employed Raman amplification with other amplification mechanisms such as Erbium. In fact, recent works have proposed new schemes for random distributed feedback generation based on Erbium-doped fiber or implementing Brillouin random lasing, Ytterbium-Brillouin or Erbium-Brillouin [125,[128][129][130][131][132][133][134][135].…”

An overview of truly remote fiber optic sensors is presented in this work. It starts with a brief introduction of fiber optic sensor networks, showing their advantages and multiple applications. Then, the definition of truly remote networks is provided, and their main challenges discussed, such as increasing the sensing distance and the number of sensors interrogated. Several multiplexing techniques have been compared, such as wavelength, time and coherence division multiplexing. In relation to this, the most recent works showing multi wavelength fiber lasers for wavelength division multiplexing have been grouped and their versatility analyzed. Finally, recent and relevant truly remote fiber optic networks have been gathered and some of the most representative schemes explained in detail, comparing their multiplexing capability and the remoteness of the monitored sensors. Random distributed feedback fiber lasers form part of a number of these schemes, proving the suitability of this type of lasers for their use in ultra-long truly remote sensing applications.

“…However, the erbium-doped fiber (EDF) has a uniform broadening effect at room temperature, and the wavelength competition is very fierce, which makes it difficult to achieve stable multi-wavelength output [2]. Many effective methods have been reported to solve the problem, such as inserting frequency shifter feedback [3], utilizing four-wave mixing (FWM) based on photonic crystal fibers (PCF) [4] and dispersion shifted fibers (DSF) [5], introducing polarization hole burning effects (PHB) [6], employing special EDF structures of double-core EDF or elliptical-core EDF [7], using stimulated Brillouin scattering (SBS) [8] or self-seeded Brillouin scattering [9], inducing nonlinear polarization rotation (NPR) [10] and so on. Moreover, the intensity-dependent loss (IDL) of NOLM and NALM has also been used to obtain stable multi-wavelength oscillation [11].…”

A novel interval-adjustable multi-wavelength erbium-doped fiber laser (EDFL) is experimentally demonstrated in this paper. The proposed EDFL is based on the cascaded structure of two-segment Sagnac filter and nonlinear optical loop mirror (NOLM). By properly adjusting the polarization controllers (PCs), the wavelength interval and number of output wavelengths can be changed. When the wavelength interval is 2nm and 0.5nm, the number of wavelengths is 1-3 and 5-8, respectively. At the same time, when the number of output wavelengths is 6~8, the wavelengths can be tuned within a certain range. In order to compare the effects of two similar nonlinear loop mirrors on the outputs, a nonlinear amplifying loop mirror (NALM) is used to replace the NOLM in the laser cavity. The number of output wavelengths is increased to 10 when using NALM. The structure and principle of NOLM and NALM are analyzed. The influences of the two structures on the stability and output power of the laser are also discussed.

“…Such a capability arises from the fact that Brillouin gain occupies a small bandwidth of about 50-100 MHz, leading to the generation of narrower laser linewidths. Many developments have been reported for Brillouin/erbiumbased RDFB fiber lasers [10][11][12]. In [10], a multiwavelength Brillouin-erbium random fiber laser (BERFL) with a halfopened linear cavity was proposed.…”

The impact of Brillouin pump (BP) preamplification on the performance of multiwavelength Brillouin-erbium random fiber lasers (BERFLs) is investigated in this work. Three different schemes-without BP preamplification, single BP preamplification and double BP pre amplification-are compared in terms of performance optimization. The experimental results suggest that the single BP preamplification scheme achieves the best performance. When the BP wavelength is set to 1550 nm, the single BP preamplification scheme has eight channels, which is higher than the four channels achieved with the double BP preamplification scheme and the two channels achieved with the scheme without BP preamplification. In terms of the threshold power, the single BP preamplification scheme records the lowest value of 6.8 mW, as opposed to 13 mW and 12.7 mW recorded for the scheme without BP preamplification and the double BP preamplification scheme, respectively. Taken together, these results indicate that the best overall performance for multiwavelength BERFLs is obtained when the single BP preamplification technique is employed.
