| Abstract: | We have observed the presence of very long delay times (~ 1 ?s) for lasing in graded barrier single-quantum-well (GB-SQW) lasers for active layers thinner than 150 A? and stripe widths below approximately 10 ?m. It is shown that an explanation of this phenomenon based on the dynamic evolution of the waveguide properties of these lasers gives good agreement with experimental results. |
