Gronenborn, J. Pollmann-Retsch, P. Pekarski, M. Miller, M. Strösser, J. Kolb, H. Mönch, P. Loosen] We show how VCSELs with elongated shapes of the emission area can achieve higher output powers and wall-plug efficiency compared to standard circular or quadratic VCSELs. We identified an improved homogeneity of the carrier concentration in the quantum wells as well as a reduced thermal resistance as the main reasons for the better performance of the rectangular shaped VCSELs presented in this article.
