An anomalous dependence of the threshold current on the stripe width isobserved for gain-guided strained-layer InGaAs/GaAs quantum well lasers. Thethreshold current increases strongly as the stripe width is reduced fromrelatively large values. This is attributed to the huge lateral loss caused byan unusually large index antiguide which manifests itself in the far-fieldbehavior. This large loss also leads to a population of higher quantized energylevels in the InGaAs quantum well strongly reducing the lasing wavelength by asmuch as 61 nm.
