In order to investigate the possibility to force an array of coupled lasers to emit a single longitudinal mode under current pulse modulation, a new hybrid device was constructed from two twin coupled-stripe lasers with external mirrors. A single narrow longitudinal mode has been obtained from the two coupled lasers. The spectrum was stabilized to less than 0.15 Ã… through a wide range of current pulse amplitudes.
