Abstract: Narrow-stripe graded-barrier single-quantum-well (SQW) lasers are relatively high-threshold current devices ( greater than 50 mA), even though made from wafers with extremely low broad-area threshold current density ( less than 300 A/cm**2). They also show a complex time-dependent lasing behavior with sequential lasing from the n equals 2 and n equals 1 quantum levels. It is shown here that these properties are inherent to narrow-stripe gain-guided SQW lasers and are dictated by the nature of the optical gain curve of the quantum well.
