An electrooptically tunable waveguide array combined with a semiconductor phase-locked laser array, to provide both amplitude shaping and phase control of the optical output. The tunable waveguide array includes an input waveguide array section with an array spacing matching that of the laser array, a tunable coupling array section for tailoring power distribution among the array elements, a tunable phase shifter array section for tailoring the relative phase distribution among the array elements, and an output waveguide array section of various possible configurations. The tunable waveguide array can be implemented either externally, independent of the laser array, or incorporated into the laser array to form a composite cavity-array.
