Structural design of random lasers with specified emission bands
The structure of the disordered gain media for a two-dimensional random laser was designed to achieve the specified emission spectrum by treating the scattering medium as deterministic cavities. A checkerboard distribution of scattering elements allows structural optimization of the scatterer array using a direct binary search method. Simulation results show that the emitted light can be concentrated in the specified wavelength bands. The effects of scatterer size and fabrication errors on the optimized emission spectrum were also investigated.
