摘要:

Polarization‐dependent lasing gain in GaAs/AlGaAs multi‐quantum‐well lasers is theoretically calculated and experimentally determined. The dipole moment representing the electron transition is calculated based on thek⋅Pperturbation method. Gain broadening due to the intraband relaxation of electron wave is also taken into account. Experimentally measured gain profiles of TE and TM modes agree well with the theoretical results.
