The size of the lasing states in ordered, partially ordered, and completely disordered systems were compared. As such, the spatial profile and dwell time of the localized states with the finite-difference time-domain (FDTD) method was calculated. By comparing the numerical results with the experimental data, the lasing threshold was reduced due to the effect of photonic bandgap on random laser.
