Abstract
We have succeeded for the first time in integrating on the same chip, two electrically independent lasers which are coherently coupled via the overlap of their lateral optical fields. Such coupled lasers show excellent single longitudinal mode characteristics which are considerably improved over that of the individual lasers. They are therefore promising devices for high data rate optical communication systems.
