Abstract :
We show the results of an experimental investigation into the limitations of the high speed direct modulation bandwidth of semiconductor lasers. It is shown that contrary to predictions based on a simple two rate equation model the resonant frequency saturates at large DC biases. The overall response of the laser diode is still underdamped when the resonant frequency saturates, thus the laser does not reach the maximum bandwidth predicted by the K factor measured at low DC bias points
