Abstract- In this paper we have investigated photon dynamics in two ground state and exited state levels of an InAs-InP quantum dot (QD) laser system , numerical models that based on rate equation are presented and is calculated by using fourth order Runge- Kutta method . As well as, numerical results for variations of photon densitiy and variations of optical gain in different volume density of quantum dots are also presented and discussed. The effect of volume density of quantum dot on turn on delay of laser has also discussed.
Keywords: Energy level, Optical gain, Volume density of quantum dot, Quantum dot laser, Rate equations
