Resumen
Using theoretical fitting to measured transverse far field patterns in Ga0·86In0·14As0·13Sb0·87/Ga 0·73Al0·27As0·02Sb0·98 DH lasers emitting at 2·2 μm we estimated the value of the active layer refractive index as 3·78. This value, higher than assumed earlier based on theoretical calculations, ensures good optical confinement for this kind of heterostructure and provides a good theoretical fit with the authors' experimental data of threshold current density against active layer thickness. 29 14 1240 1241
