Abstract
We describe the characteristics of graded-index separate-confinement heterostructure (GRIN-SCH) quantum well laser structures for a wide range of quantum well thickness and graded layer composition. It was deduced that the ‘‘GRIN’’ region enhances carrier confinement and assists the thermalization of carriers into the quantum well. A maximum value of T0 of 190 K was measured for these single quantum well lasers.Keywords
