A random laser on the optical fiber facet is constructed by dipping an optical fiber end face into the solution of polydimethylsiloxane doped with rhodamine 6G organic dye and silver nanowires. The PDMS film doped with rhodamine 6G acts as the active waveguide layer, and the silver nanowires provide a three-dimensional plasmonic feedback. The plasmon resonance of silver nanowires significantly improves the pump efficiency of the random laser. The most output energy of random laser concentrates in a small angle range along the axis of the optical fiber. This fabrication technique provides a simple and efficient way for the fabrication of random lasers on the optical fiber facet with low cost.
