Abstract :
The in-phase lateral- and single-longitudinal-mode operation of a 1.5- mu m GaInAsP/InP laser array was demonstrated. The array consists of a positive-index-guide multiple-stripe array region and an unguided grating filter region. The advantage of this laser array is experimentally confirmed by comparing with the multiple-stripe DFB type laser array without the grating filter.<>
