An AlGaAs dual-stripe laser, where each stripe has an SBH configuration, has been fabricated by means of chemical etching followed by liquid phase epitaxy. Phase-locked oscillation is observed under pulsed and CW operations. This is confirmed by the coalescence of the two longitudinal modes, as well as by the interference fringe measured in the far-field radiation pattern.
