Abstract :
Two-dimensional, coherent, grating surface-emitting AlGaAs laser arrays consisting of forty (4*10) active elements have been fabricated with a multiple quantum well structure. The elements of the array are index-guided ridge lasers, connected laterally by Y-branches and coupled longitudinally with passive ridge waveguides containing second-order distributed Bragg reflectors.
