High-power semi-insulating blocked planar buried-heterostructure (SIPBH) lasers were grown entirely by atmospheric organometallic vapor phase epitaxy (OMVPE) by using a novel dilution scheme for the trimethylgallium and AsH/sub 3/. Current thresholds as low as 20 mA and differential quantum efficiencies greater than or equal to20% per facet at 1.3 and 1.5 ..mu..m were obtained with power outputs of about 25 mW/facet. These results are similar to SIPBH lasers where liquid phase epitaxy was used to grow the active layer, but because of the better planarity and uniformity of OMVPE-grown material, it appears possible to grow material that can give a high yield of distributed feedback lasers.
