Blue lasers a key element for new generation of CD and DVD systems

Abstract

The theoretical and experimental investigations of the dynamics of blue InGaN quantum well lasers with different designs are reported in this paper. The bifurcations, which are on the origin of the phenomenon of self-pulsation are identified and the effect of the lasers parameters on laser dynamics is discussed. It is shown how different laser structures can be used to control laser behaviour. Finally, an agreement between the results of numerical calculations and experimental measurements is demonstrated.
