In this paper we report and analyze some interesting properties observed for gain-guided GB-SQW lasers. For narrow stripe widths (less than or equal to10 ..mu..) and thin active layers (less than or equal to150 ..cap alpha..) we observe a long delay time for lasing and abnormal increase in threshold current density. To explain this behavior we developed a model of waveguiding that takes into account the effect of heat profile generated along the junction plane due to carrier injection, and good agreement with experimental results is obtained.
