Diffraction-coupled arrays of InGaAs/InP buried-heterostructure lasers are reported. These arrays, fabricated by ion-beam-assisted etching and mass transport, have a novel scalloped mirror at the end of the coupling section that greatly increases the coupling between stripes and reduces the feedback into the same stripe. Far-field patterns show sharply defined lobes that are as narrow as 3. An output section with cylindrical mirrors was incorporated into the arrays to increase the power in the central far-field lobe. Threshold currents as low as 150 mA were obtained for eight-stripe arrays.
