摘要
An efficient method for modelling the electronic structure and optical properties of quantum wires (QWRs) is proposed. The optical properties of an InGaAs/InP QWR laser are calculated in the framework of the k(.)p method, with the conduction-band nonparabolicity included for the first time. We show that high material gain can be achieved (8000 cm(-1)) at room temperatures for X polarization. However, due to a small confinement factor lasing can be achieved only at low temperatures (T=15K) which is verified by experiment.
