摘要：

Measurements of subthreshold spectra on SCMQW (separate confinement multiquantum well) lasers with the number of wells varying from three to nine have led to the determination of the carrier-induced differential refractive index dμ/dN∼-3.6 x 10-20 cm3. This value is 1.8 greater, compared to the case of conventional bulk lasers. This study allows for a better understanding of quantum well lasers parameters such as spectral linewidth enhancement factor. It will be also useful for the design of tunable lasers. © 1990 IEEE
