CONSTRICTED DOUBLE HETEROSTRUCTURE SEMICONDUCTOR LASER ABSTRACT OF THE DISCLOSURE The invention is a semiconductor laser which includes a substrate with a pair of substantially parallel grooves in a surface thereof with a mesa therebetween where the height of the surface of the mesa above the bottom of the grooves is different than the height of the major surface of the substrate above the bottom of the grooves. Layers deposited on this substrate exhibit an increased taper in thickness in the lateral direction.
