Carrier charge imbalance and self-consistent potential effects are systematically studied regarding the optical properties of separate confinement quantum well lasers. Numerical modeling of the typical InP-based laser structure shows that violating the quasineutrality in the vicinity of quantum wells results in a dramatic change in a fraction of carriers trapped in the lasing subbands, and a corresponding modification of laser waveguide properties. © 2000 American Institute of Physics.
