Abstract

We demonstrate random lasing emission in an active planar slab of AlGaAs/GaAs randomly perforated with subwavelength circular holes. Spectrally-resolved imaging of both the diffusion in the passive regime together with the lasing emission allows identifying exteneded lasing modes in the weakly diffusive regime.
