A model for GRIN-SCH-SQW diode lasers

A comprehensive model for graded-index, separate-confinement-heterostructure, single-quantum-well (GRIN-SCH-SQW) Al/sub x/Ga/sub 1-x/As diode lasers is presented, and compared with experimental data. The model combines many individual features not heretofore included together, and gives good agreement with gain-vs.-current density data for different structure variations. In addition, the threshold temperature dependence agrees well with data for typical laser conditions, and the high-gain kink in T/sub 0/ versus temperature is qualitatively explained.<
