The transmission pace of information communique structures is forecast to extend exponentially over the following decade. improvement of either Si-based high-speed drivers in addition to III-V-semiconductor-based high-speed vertical hollow space floor emitting lasers (VCSELs) are necessities for destiny ultrahigh data-rate structures. This thesis offers: - a survey of the current state-of-the-art of VCSELs - a scientific research of many of the results restricting current VCSELs - a listing of ideas to beat current limits - special growth in modelling, fabricating and trying out the at present so much complex VCSELs on the commercially most crucial wavelengths.

Moreover, these phenomena are not independent from each other but build in their strong and commonly non-linear interactions a complex picture of the physical processes inside of a device. For example current flow generates heat, temperature changes affect among other electrical resistance and refractive index of semiconductor materials, presenting photons change carrier concentrations due to absorption and so on. Many physical processes naturally arise from interactions between different fields or particles.
