Abstract

We report for the first time to our knowledge, the random laser emission from surface corrugated waveguides. Discrete lasing modes, super narrow spectral linewidth, and the existence of lasing threshold behavior have been observed. A theoretical model combining transfer matrix method and effective refractive index method was presented to explain the random lasing phenomena.
