Abstract
We have investigated the effect of size of InAS/InP (311)B quantum dot (QD), both height an diameter, on electronic levels and hence transition energies through k.p model, with focus on application in QD lasers. Therefore the results have been included in dynamic analysis based on coupled differential rate equations, to obtain variation of laser properties such as gain, photon number and modulation bandwidth in accordance to different experimental outcomes. This demonstrates that larger modulation bandwidth of ground state is given by QDs with smaller diameter but larger height however for excited state larger modulation bandwidth is given by smaller diameter and smaller height.
