Abstract
Process for producing an injection laser and laser obtained by this process. The active layer is weakly n doped. The same mesa is used for carrying out a proton implantation and a zinc diffusion. The active stripe is transversely limited by two homojunctions and two index jumps and the final structure is planar. In addition, there is an auto-alignment of the implanted and diffused zones. Application to the construction of lasers used in optical telecommunication systems.
