“…The intense research has resulted in a wide range of applications and improvements. Many studies have been carried out to enhance the already promising inherent features of RDFB-FL, for instance, the optimization of the output power [104][105][106][107], relative intensity noise transfer [108,109]and thermal noise [110]. In addition, their spectral and statistical properties have been analyzed in [111][112][113] and a variety of configurations have been proposed implementing polarized pump or linearlypolarized outputs [114][115][116][117], mixing different fibers in the gain media [118], short cavities [119,120] and tunable [121], multi-wavelength [57,[122][123][124][125] or super-continuum output [126,127].…”

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.

“…For the distributed amplification, the power distribution is the focus of consideration, and for point-sensing system it could be the threshold. In fact, a model that can quickly calculate these features in a half-open cavity RRFL is highly desired for most applications [20,21], as it would help to the system designer to grip the major outcome without going through all the details. The first analytical RRFL model with formulas describing power features was proposed in Ref.…”

The power-relevant features of Raman random fiber laser (RRFL), such as lasing threshold, slope efficiency, and power distribution, are among the most critical parameters to characterize its operation status. In this work, focusing on the power features of the half-open cavity RRFL, an ultrafast convergent power-balance model is proposed, which highlights the physical essence of the most common RRFL type and sharply reduces the computation workload. By transforming the time-consuming serial calculation to a parallel one, the calculation efficiency can be improved by more than 100 times. Particularly, for different point-mirror reflectivities and different fiber lengths, the input-output power curves and power distribution curves calculated by the present model match nicely with those of the conventional model, as well as with the experimental data. Moreover, through the present model the relationship between point-mirror reflectivity and laser threshold is analytically derived, and the way for improving RRFL's slope efficiency is also provided with a lucid theoretical explanation.

“…The standard approach to reach random lasing is to use solid‐state powders, including semiconductors, and dye solutions with scatterers . More advanced variant is a fiber laser with random distributed feedback . Recently, random lasing in the Anderson localized regime was reported both in 2D disordered photonic crystals and disordered optical fibers .…”

Different Regimes of Ultrashort Pulse Propagation in Disordered Layered Media with Resonant Loss and Gain

Different optical nanostructures containing both loss and gain components attract ever-increasing attention as novel advanced materials and building blocks for a variety of nanophotonic and plasmonic applications. Unique tunable optical signatures of the so-called active metamaterials support their utilization for sensing, imaging, and signal processing on micro-and nanoscales. However, this tunability requires flexible control over the metamaterial parameters, which could be provided by involving a set of nonlinear interactions. In this paper, a method of governing ultrashort pulses is proposed by varying the level of a population difference disorder in a random active metamaterial. This enables us to deliver three different interaction regimes: self-induced transparency (low disorder), localization regime (moderate disorder), and light amplification (strong disorder) corresponding to strongly different light pulse speeds. Since this control could be realized via rather plain tools, like simple pump tuning, the proposed disordered medium opens a room of opportunities for designing a peculiar active component for a whole set of highly demanded optical applications.
