The advantage of the tunneling injection process stems from the fact that it avoids hot carrier injection, which is a key performance-limiting factor in all semiconductor lasers. The tunneling injection process is not fully understood microscopically and therefore it is difficult to optimize those laser structures. We present here a numerical study of the broad band carrier dynamics in a tunneling injection qua","authors_text":"A. K. Mishra, F. Jahnke, G. Eisenstein, I. Khanonkin, J. P. Reithmaier, M. Lorke, S.
