We have anelyzed the displacement damage effects on quantum dot lasers theoretically and deduced the relation between the radiation-induced threshold current change and the neutron fluence. The neutron radiation experiment for quantum dot lasers are also carried out to examine the displacement damage coefficient of the non-radioactive recombination rate. The formula fits the experimental data very well, and can describe the trend of the laser performance under electron irradiation. It can also predict the behavior of quantum dot lasers under radiation environment and is valuable for practical application.
