Abstract

The linewidth enhancement factor (LWEF) in single quantum-well lasers is analyzed theoretically and experimentally. The LWEF clamps with increasing carrier density and the correct LWEF at the gain peak is affected by the density dependence of the gain maximum. Calculations show that designing laser structures is possible, wherein the LWEF does not have to increase with increasing pump level.
