Abstract
The dependence of the threshold far-field behavior on the stripe width and index antiguiding is investigated theoretically using realistic carrier-density profiles in stripe-geometry double-heterostructure lasers. It is suggested that for lasers exhibiting twin lobes in their far-field the peak separation can be used to estimate the extent of index antiguiding. The results indicate that the thershold for the appearance of far-field lobes in narrow stripe lasers can be pushed to a higher drive-level by shortening the cavity or by decreasing the facet reflectivity.
