Abstract: A method for improving the current confinement capacity of a double heterojunction laser by using a high energy implantation of oxygen in the regions of an injection laser surrounding the active region of such laser so as to make such regions semi-insulating.

Abstract: 2-Dimensional injection laser matrix with a number of resonators having bent ray paths has reflecting faces cutting the individual pn-junctions at angles different from 90 degrees, which further guide the radiation coming from the individual emitting pn-junctions over other reflecting faces defining the resonator ray paths or grating like structures to the emitting junction. The prodn. of the matrix and the appts. used are also claimed. The injection laser consists of closely-packed 2-dimensional units and emits light parallel to the direction of the stimulating source.
