We present the development of theoretical model based on multi-population rate equation to assess the derivative optical gain and chirp characteristics from the multiple states broadband InGaAs/GaAs quantum-dots laser. Our results show that the linewidth enhancement factor from the ground state is slightly larger but in the same order of magnitude as the values obtained in conventional quantum-dot lasers. This study is important in proving the competency of this novel device for diverse applications.
