Abstract :
Spatial and spectral mode measurements on gain-guided GaAs multiquantum-well lasers yield greatly reduced spontaneous emission K-factors in lasing modes as compared to conventional lasers. Small K-factors lead to narrow far fields and to nearly single longitudinal mode operation in gain-guided quantum-well lasers
