1. An article comprising tunable laser means comprisinga) a first body having a major surface and comprising a semiconductor layer structure including multilayer semiconductor reflection means and an active region, located between said reflection means and said major surface, with said reflection means and active region being essentially parallel with said major surface, and further comprising first contact means that facilitate flowing an electric current through said semiconductor layer structure such that the laser means has a radiation output;

  • b) a quantity of electro-optic material; and

    c) second contact means that facilitate applying an electric field across said electro-optic material;

    Characterized in Thatd) the quantity of electro-optic material comprises a layer of electro-optic material in contact with said major surface; and

    e) the second contact means comprise a first and a second contact layer, with said first body comprising said first contact layer and a second body comprising said second contact layer, the laser means further comprising means for maintaining said second body in fixed relationship with said first body.
