Abstract
A II-VI compound semiconductor laser diode includes a plurality of layers of II-VI semiconductor forming a pn junction supported by a single crystal GaAs semiconductor substrate. The layers forming the pn junction include a first cladding layer of a first conductivity type, a second cladding layer of a second conductivity type, and at least a first guiding layer between the first and second cladding layers. A CdZnSe or other II-VI semiconductor quantum well active layer is positioned within the pn junction. Electrical energy is coupled to the laser diode by first and second electrodes.
