The threshold is significantly reduced compared with the bulk solution due to optical guiding and scattering. � OSA 2016.en-USFibersLaser beamsOptical fibersBulk solutionsDye solutionsHollow-core photonic-crystalMetallic nanoparticlesOptical guidingRandom lasersPhotonic crystal fibersConference Paper
