Abstract
This invention relates to a laser array which can produce at least two independently addressable laser beams, each of which has fully index-guided buried optical waveguides. Specifically, the array is formed by a two-step impurity disordering process, which simplifies the fabrication of laser arrays and optoelectronic integrated circuits.
