Summary form only given. Since the fust blue-green diode lasers were reported by 3M and the Brown/Purdue group in the summer of 1991, a number of layered arrangements have been used for laser diodes emitting f¿ green to blue. In the earliest devices, and the configuration adapted by several other groups,one to three quantum wells of (Zn,Cd)Se were used, the optical confinement was provided by an intrinsically non-pseudomorphic structure having dislocation arrays between the Zn(S,Se) outer cladding layers and the ZnSe waveguiding/banier regions. A second type of structure, primarily employed by the Brown/Purdue group, was pseudomorphic and contained (usually) six quantum wells of (Zn,Cd)Se imbedded in Zn(S,Se); the configuration served as a compromise between optimum electrical and optical confinement. These MQW structures relied on the lower optical refractive index of the (Zn,Cd)Se wells to provide the optical waveguiding.
