Abstract
The power-dependent part of the linewidth of GaAs/AlGaAs GRINSCH-SQW flared waveguide lasers has been determined from FM noise measurements. For the linewidth-power product a low value of 4 MHz mW has been found, which can be related to the small spontaneous emission coefficient βsp≃(3.7±1)×10-6 and a linewidth enhancement factor α≃1.2±0.5
