Abstract

Using a delay differential equation model for a two-section semiconductor laser, we have found a new bifurcation scenario leading to stable mode-locked operation with normal dispersion properties of the light travel. The pulse profile is asymmetric, with a slower leading edge and a negative chirp. We classify the parameter space in which this regime exists as a Busse balloon and describe its boundaries.
