Abstract-In this article numerical methods based on rate equations are presented and to study the dynamics of photons emission in two ground state and excited state level an InAs-InP quantum dot (QD) lasers system is used that is calculated by using fourth order Runge-kutta method. In addition, numerical results for the variations of photons population and the variations of output power for different non-homogeneous broadening factors are also presented and discussed. The effect of non-homogeneous broadening factor on turn on delay of laser has also discussed.
Keywords: Energy level, Non-homogeneous broadening factor, Output power, Quantum dot laser, Rate equations.
