Abstract
Mechanisms causing non-linearity of power-current characteristics (PCC) of quantum-well lasers at high injection levels were studied both experimentally and theoretically. A critical injection current that switch on a nonlinear PCC mode was found to depend to a great extend on the resonator length (on the threshold concentration). The PCC non-linearity is well described within the framework of the gain saturation mechanism where a dependence of the gain coefficient on the radiation intensity at high injected carriers concentration is taken into account.
