“…More control over the lasing properties was obtained by embedding the dye and the scattering nanoparticles in a polymer optical fiber in a bottom-up approach [103,104]. More recently, a liquid-filled hollow fiber configuration was used [105] to realize a plasmonic random laser, where they replaced the POSS scattering centers with gold nanoparticles.…”

Doc. ID 239686)Random fiber lasers blend together attractive features of traditional random lasers, such as low cost and simplicity of fabrication, with high-performance characteristics of conventional fiber lasers, such as good directionality and high efficiency. Low coherence of random lasers is important for speckle-free imaging applications. The random fiber laser with distributed feedback proposed in 2010 led to a quickly developing class of light sources that utilize inherent optical fiber disorder in the form of the Rayleigh scattering and distributed Raman gain. The random fiber laser is an interesting and practically important example of a photonic device based on exploitation of optical medium disorder. We provide an overview of recent advances in this field, including high-power and high-efficiency generation, spectral and statistical properties of random fiber lasers, nonlinear kinetic theory of such systems, and emerging applications in telecommunications and distributed sensing.

A theory of light–matter interaction in plasmonic nanofibers is developed. When probe light propagates inside the nanofiber, it induces surface plasmon polariton (SPPs) and electric dipoles in metallic nanoparticles. The dipoles interact with each other via dipole–dipole interaction (DDI). The energy of photonic bound states in the presence of the SPP and DDI fields are calculated. It has been demonstrated that the number of bound states can be controlled by the strength of SPP and DDI couplings. The spontaneous decay rate for the quantum emitters have been calculated and it is found that decay rate is enhanced when the exciton energy is in resonance with the bound photon energy. Further, it is predicted that the spontaneous decay rate also enhances when the exciton and SPP energies are in resonance. Finally, the photoluminescence in nanofiber is calculated using the density matrix method. The authors' theory is compared with experiments and found a good agreement between theory and experiments. It has been demonstrated that the quenching of the photoluminescence intensity increases as the concentration of the MNPs increases. The findings of the paper can be used to fabricate random lasers and also for inventing new types of nanosensors and nanoswitches.

demonstration of RFL by inserting TiO 2 particles and rhodamine 6G dyes into the hollow core of a photonic crystal fiber, which opened the research field of RFLs. [15] Subsequently, both coherent and incoherent RFLs based on various fiber structures have been demonstrated. [16][17][18] These RFLs have several merits like low threshold, directional output, and low-cost fabrication, indicating that they are superior to other conventional RLs in some applications. [16] According to the feedback mechanism, RFLs can be generally classified into two categories: (1) RFLs based on common single mode fibers with the feedback provided by Rayleigh scattering and Raman effect, [19][20][21][22][23][24][25] (2) RFLs based on specific fibers (e.g., liquid core optical fibers, polymer optical fibers, and erbium-doped fibers) with the feedback provided by doped particles or randomly distributed Bragg gratings. [16,[26][27][28][29][30][31] For the first type of RFLs, their length are normally more than several kilometers, which limits their applications. [18] Conversely, the size of the second type of RFLs is in the centimeter scale. [26] Moreover, the properties of the second type of RFLs (e.g., shape, size, lasing wavelength, and laser threshold) could be tuned via controlling the fiber materials, scatterers, and optical gain medium. [27,28,32] As a result, the second type of RFLs can be regarded as ideal experimental systems for the investigation of random lasing with novel materials (like plasmonic materials), which have already been reported in several studies. [17,33,34] However, these studies mainly focus on experimental studies and corresponding theoretical models are still lacking to date. There is a need to find an effective numerical model to describe the lasing dynamic in the RFLs. Moreover, although RFLs have great potential in various applications, no practical application has been reported in the past studies.In the present work, we have demonstrated polymer optical fiber RLs (POFRLs) by doping TiO 2 nanoparticles and Rh640 perchlorate dyes into the core of the POFs. The optical gain in our POFRL was provided by Rh640 perchlorate dyes which are widely used organic luminescent dyes for many dye laser systems. The TiO 2 nanoparticles worked as scatterers to provide multiscattering events for light propagation and the resulting scattering strength is in the weakly scattering regime (scattering mean free path l s ≫ emission wavelength λ). Multimode and coherent random lasing was observed in our POFRLs, which 1D random fiber laser is a novel fiber-based laser, which exhibits many unique optical properties and shows great promise for various applications including speckle-free imaging. A multimode and coherent polymer optical fiber random laser (POFRL) is successfully fabricated by doping TiO 2 nanoparticles and Rh640 perchlorate dyes in the core of a polymer optical fiber (POF). The waveguide effect provided by the POF greatly increases the multiscattering events for light propagation and results in laser cavity with muc...
