In this work, we present a simulation method for estimating the output spectrum of a laser at threshold and we experimentally verify it. The simulation method is based on a T-matrix formulation of the laser mode propagation. The steady state electric field is calculated in the resonator at the lasing threshold and gives the output spectrum of the laser. The validity of this method is experimentally verified by obtaining the spectra of DBR lasers at threshold and comparing them with the calculated spectra.
