Large scale networks of semiconductor lasers are a long shought after technology. Since the demonstration of semiconductor lasers they have been heavily involved in investigating nonlinear dynamics and chaos. However, scalable networks with the potential for hosting 100s of such lasers have never been achieved. We will demonstrate individual and addressable single mode pumping of densely packed, homogenized arrays of quantum dot micropillar lasers. We are able to pump more than 50 devices and realize all-optical nearest neighbor coupling. It is the first time such large semiconductor laser networks have been demonstrated, and our concept is scalable in principle until over 100.000 lasers. Our experiment opens new avenus for fundamental nonlinear dynamics experiments and high profile applications such as novel neuromorphic computing concepts and material processing.
