The problem of current spreading and diffusion in oxide stripe lasers leads to two coupled boundary value problems. This paper presents an efficient method for the simultaneous solution of these two problems based on the conversion of the two-dimensional Laplace equation representing the current spreading into integral equations by means of a contour integral. The power of the method is illustrated by its application to a coupled triple-stripe laser. Highlights of the numerical method are discussed.
