Abstract
A semiconductor laser comprises a plurality of laser sections (10, 11, 12) defined in a body and isolated electrically from one another. The active region (14) of each section are optically coupled together and electrical connections (9) connect the sections in series and provide connections to an external drive current source. In a practical embodiment the laser is constructed in planar form in a body (16) of semi-insulating material and wells (23a, 23b, 23c) are etched into the body and are provided with metallization (24) which forms the electrical connections. The active region (14) extends continuously through the body with separate p-type anodes thereabove and separate n-type cathodes beneath the active region and extending on either side thereof.
