A linear array of closely spaced Al GaAs lasers is mounted on an Si heat sink, Schottky diode detectors formed on the same Si chip provide optical sensing and electrical feedback signals for output power stabilization of the individual laser elements. The performance of a typical pair of adjacent devices is tested showing that electrical and optical crosstalk between lasers is virtually eliminated.
